Based (loosely) on the Classics Ultimate Battle Optimus Prime: Not sure I'm entirely happy with the way his smokestacks on his shoulders came out on the sideways motions, but they didn't look good any other way either. One thing I am happy with are the eyes. I initially had trouble shading them, so I went with an SD Gundam styled "pupil" in the centre, then shaded outwards from there. I think it really works with the smaller style. I think I might try a Classics Seeker next. Considering this is the first full sprite I've ever designed, I think it works pretty well.
