There are a few things wrong with this pic.  First, the expression on Steampunk's face is downplayed.  In other words, I should have drawn his head thrown back to convey more emotion.  Also, because this pic takes place at night, shading on the trees and on the background is a necessity that was sadly left out of the pic.  Further, the background is rather lackluster and boring.  In my opinion, everything else was done well . . . I especially like how his machine arm came out, more specifically the vents.  I should have added some smoke coming out of them, though.
