Cindus ... two things. First I edited your post to make the pictures fit one above another so that they did not expand the screen to the right and make it hard to read the other posts.
So you and others know, just put a couple of spaces between each picture and they will post vertically like this. If you post pictures without spaces between them ... they will load horizontally and mess up the screen.
Secondly, I like what you did with the black. It's so hard to make it look good when it's not specially lit ... it goes flat looking. But you rescued it from that problem ... but using interesting shapes (#2 & #5), sheerness to see the skin underneath (#5 & #2) and the play of the black against the skin at the chest and the use of shiny satin (#2 & #3). If you had not done that, the clothing would have been flat and boring, since no special lighting was used to show off the fabrics or details. Well done!
I like the model, too ... she's strong looking ... perfect for this look.
