animation backgrounds

[phonicsmonkey]

These are some backgrounds for some scenes in my animation for school. Gonna do some jiggery pokery with green screen to get some characters in there. Sorry if its a little dark, looks fine on the computer i model on, but on this one it looks soooooo dark....but then on a tv screen it looks just right, so i'm figuring its just this monitor so you guys wont have trouble seeing it.
Modelled in 3dsmax 6
This is a dirty scary alley our characters get attacked in:

This is the opening scene, its raining on some tropical leaves, havent quite worked out how to make depth of field look good yet:
