Outline is pretty much done. Just posting it here to see if it could be improved before I attempt to shade it. :|
Id work on the outline a bit more. Remember your using a 3/4ths perspective for BYOND games.

Check out this edit, I don't want to post the actual image, for it would be too big.

Okay I made my own edit and put a bit of simple shading on it, what do yas think now?
