Cool! I'm into photography myself as well. Used to attend school for it, but that ended after a semester. Just a hobby for now, maybe it'll grow into something one day.
I don't know if I like the textures on the drawings, as they' don't necessarily belong. But all in all, good work!
How much did the websites give you for making the backgrounds? I was interested in doing that at one point just couldnt find the right site to start up on.
I like your avatar more than anything. It's quite hard to see the threads in any detail, but from what I can see they look fairly well done.
As someone else said, the illustrations would be much nicer without a texture overlay.
