It's kind of hard to tell where you're at because these are pretty bad photos. But, from what I can see you have a fairly good grasp of light and shadows (at least with the back and white), and that you're doing some nice studies. The fish/head (fishhead?)thing is a little rainbow for my tastes, but I guess I'd have to see more stuff before commenting on it.
The detail of the guy talking to the kid in the first one really gives it a sense of story, and I like that. My only problem with the rainbow is that some of the colors mix together to make mud. If the coloring were digital, or more discreet (as opposed to blended colored pencil) I think it might work better.

One thing though; get a scanner. Seriously. Or a better camera. Bad photos make your work look less awesome than it actually is.
Post more!
I like drawing, cartoons, cookies, and shiny pointy objects.
