Ok, so I don't know if I'm ever going to finish this! So I decided I'd put the finalised sketch up here for now. Please let me know if you see this up where it shouldn't be!
You can see the editing I did in Photoshop by the cleaned up characters against the dirty background, which I think looks pretty cool 0_0 I struggle with perspective on paper, so I resized the characters digitally because I got sick of redrawing them (which I did about 3 times).
Anyway, enjoy and if you have any suggestions for colouring this, let me know! I'd prefer suggestions on colouring style instead of actual colour choices.
