You posted an awful lot to comment on
So, I'll just comment on the photos I like the most. I think the self portrait (shadow) on the graf is a good shot. I like the choice of background and the angle, it prpduces just enough tension to make it interesting. A nice dark shadow as well on a good background.
The other I like is the flowers and graf. It is a good urban photo. However it needs to have better dof. The flower in the front should be sharper and more graf is needed to provide a more dramatic photo. It is a good idea, but I think the execution could be worked on to make it a much better photo.
