He could some cucumber slices for those eyes.
I spent the last couple of weeks changing David's look. I originally had him in a straight jacket to get the idea across that he's a rather nutty guy who acts on impulse, but I ultimately decided that the look separated him too much from the rest of the group. Like the others, he's a high school kid from the same school (or at least he was when he died), so I gave him a school uniform. But, he's been dead for a while, so I wanted his uniform to be of a different design to show that he's from a generation or two ago. As for him being a bit crazy, I figured his actions would get that across.
You can also see from the eraser marks in the turnaround that I was figuring out how tall he should be. At first he was as tall as Reason, but if I want Reason to be tall for his age, I better make sure he's at least the tallest of the group of main characters. So I made David half a head shorter.
