I'm stuck.

[A Can Of Win]

First off I'd like to say that I don't know if this is the right section or not.

Ok, so I started working on this:



And now I have no clue what to do. I did the selective coloring and now I'm kind of clueless as to what I should do next. Does anyone have any ideas? Or maybe take the .PSD and work on it. I'm just completely stuck.

UPDATE:



I'm still sort of lost for effects but as of now I am really pleased with the depth and lighting. Any suggestions?
