So anyway, I am one of the character designers for the commercial. If I had to guess why this is, I would have to say that I was either vastly underqualified compared to my peers to do anything else or because I threatened to leave the class if I was put on the 3D team...

This first one is my favorite personally. Originally, he was in a more classic wheelchair because I thought the sillouette was much more interesting with the handles on the chair, but when I got to working he seemed to fit better in a power chair (which almost got tank treads).
Ultimately this design -though popular- was passed over because he looked too much like a former president and not enough like a generic war veteran. Personally, I love the face. The expression is great.

This is the design we went with, though there are going to be a few modifications before it's done -we added an oxygen tank, corncob pipe and slippers instead of loafers. I still like this one, though personally I think it's a little too generic, it's also pretty much exactly what I pictured the first time we began talking about this.
What really seemed to sell this one to the group was the pull-string...they REALLY like that pull-string idea. However, I am personally happy again with the face, especially the glasses which took quite awhile to get right.
Eventually this will be a 3d model (thankfully, I am not in charge of making it) which will be rigged along with the children for the commercial which will be completed hopefully by the end of next quarter.
I will of course add more on this project as it becomes available. And now for your viewing enjoyment, the children I designed for the commercial. The only thing that survived to the final design (headed by my vastly more talented teammate) was the curly hair from the middle kid.
