Welcome to the Fashion Spot!
The styling is "you" and therefore is interesting. You do not have to style from high end labels .... it's more about an interesting or unexpected mix. However, people will tire of seeing that same style ... so mix it up a lot.
I especially like the second set of pics .... to celebrate your graduation. I like the mix of the things around you and espeically the shot of the bracelet .... very inventive. And it looks professionaly done, to me.
And I love the Mademoiselle la Comtesse shot ..... for the depth of the background, the lighting and the dramatic look of the model, which, despite the dramatic background, is the main focus of this photo ... due to the forced perspective.
I am a stylist in Los Angeles, and I do mostly commercial stuff (not high fashion, just regular clothes) ... but I've worked with a lot of fashion photographers and have seen their portfolios ... and we often critique each other's shots.
So, I can offer some ideas and thoughts about your photos and your blog:
1. You say you wish to show off your photography. Therefore, your blog will serve as a portfolio too. So, remember, as they have always told me .... your portfolio is only as good as your worst shot in there ... so edit your photos, ruthlessly. This advice is to serve as a critique of the blog as if it were a fashion photography portfolio ... so I'm only talking about the photos you take and post in this blog.
2. When you shoot "fashion", you must remember that is is about the clothes .... not the background. Yes ... the background can offer a sense of the theme that you are trying to get across, so it's important. But if the clothes are not the main focus ... you have not succeeded in shooting a good fashion photo. That is exactly why I like the bracelet shot ... it's all about the bracelet .... excellent!
3. Do "fashion stories" ... that means you should have a theme or a concept to the photoshoot. You must start with an idea of what the pictures will be about. You can start with the clothes ... then decide what the setting should be. Or you can find a setting, and then style the looks to work within the setting. But they must work together, to get your vision across.
Example: If you are shooting a dark goth outfit, you have a couple of choices. You can go with the goth, and find a dark and mysterious location ... and this is the easiest way to have a good story. Or you can decide if you want to make the setting in opposition to the clothes. But this does not always work ... it's has to be strong opposites and there has to be compelling reason why the model is there in that outfit and the entire picture has to explain it (lighting and posing is just as important as background). So, trying this does not work most of the time. Pretty background with strong, dark styling is very, very hard to do well, to make a good story. Find a less pretty backdrop ... maybe under a bridge, against some grafitti, in an alleyway .... things like that. Still interesting ... but better suited to "goth".
My suggestion ... begin with working "with" the style of the clothes, not against it. Once you get that down, then you can experiment with opposites.
4. Backgrounds: Careful about not placing your model in or close to a background. It's too distracting. If you are close, use a shorter depth of field to bring the model into sharp focus, and blur the background (If you are studying photoghraphy, you will know how to do this with appetures and f stops, etc.) Be careful that the background doesn't overshadow the model, as it does in the lilacs shots. And don't sit in the garden ... it looks like a common snapshot that your mother would take.
Now, the Mademoiselle la Comtesse shot is a great example of how to use a background to your advantage .... and how to get a story out of opposites. It makes visual sense with that outfit. Why? Because it looks like a little girl who is lost, way out in the countryside, all alone, unsure of herself, perhaps a posh city girl in a lonely and slightly foreboding place ... a "story". And because the background just works with the story ... it's scary and pretty at the same time. And because, as I said before, it makes the model the focus of the picture.
5. Suggestion ... unless the story is about the handbag, get rid of it. It only distracts from the outfit. If it's about the bag, then do closeups, making sure the clothes complement the bag, not the other way around.
6. Get someone else to model ... and switch it up often. You are very cute, that is not the problem. The problem is that if you are both the photographer and the stylist, too ... you can't effectively be the model and still get good pictures. In fact, a professional photographer would not even try to style the shoot himself ... he might approve the "looks" but he'd have the stylist there as his second set of eyes to make sure the clothes look good, while he made sure the posing, lighting and background was working. Doing both is hard enough ... you need to stay behind the lens, if this blog is about your photography.
To learn more about fashion photography .... study the fashion magazines ... look at the backgrounds, the lighting, the posing, the focus and depth of field, and see if you like how they put their "stories" together.
Now, I've broken a rule here and taken this nicely off topic ... my comments are more about photography and styling than about your blog (only slightly related). So ... if you want to discuss fashion photography more, you might be interested in some of these threads:
