^^ This is a really good attempt, however, here are some pointers for the black version:
Is this handsewn? There are puckered seams and I don't know if you want it to look like that.
The zipper is a big no-no. What look are your going for? Invisible, exposed, centered?
On top of that, the zipper is not properly installed. The zipper pull should be in line with the very top or 1/8" below the very top of your center back seam. The excess tape is supposed to be folded inside when you sew the zipper.
Also, your seam that it going across the back is not matching up at the zipper area, your right seam is higher than your left.
I really applaud your efforts and if you incorporate these directions, the quality will take it to the top!
