A good start, but I think there's still a lot that can be done to optimize the space usage. For example, there's a lot of blank space on the shoes that can be fixed by reorienting and scaling things a bit (see attachment). Also, we talked about stretching the pants... I'm going to do a bit more research and get back to you on that -- I really don't think the stretching is that bad. If there were some distortion and skewing going on, I'd agree with you 100%, but I don't think a 20-30% vertical stretch is going to hurt anything.
The jersey is a big concern, though... and probably what you put the most work into, too. But it's only using up about 50% of the area, if that. We really need the area on this one, as it will probably contain most of the detail. This is why I suggested breaking it along the seams of a real jersey, since the designs would naturally break there and we wouldn't have to worry about lining them up. You've done that for the most part. You just need to break the arms off and place them next to it in order to make it more square-shaped (then scale everything up, obviously).

But good work -- I appreciate you guys working on this!
