If it seems weird that his jacket is yellow that's because I originally made the sketch in (darker) variations of yellow including the background. The colors were too muddled so I color corrected until I found something I liked.
I appreciate the critique, people don't seem to give them often but they are helpful. Hmm I hadn't noticed the head proportions were off but that is a problem I seem to have occasionally. Not sure why. Anyways, thanks for your comment ^^
