I realize that it's important to stick to goals, but I really think that the wookie compatibility (WC) requirement and the compactness of the chassis (which I'll simplify with just one of the measurements - wheelbase of 95") makes for WC/HoF conflicts. Obviously, looks are a completely subjective thing, but there is a lot of friendly discussion about any given design meeting the design template. On the other hand, it wouldn't be fair to deny our wookie friends the ability to enjoy what will undoubtedly be a fun package for the selfish reason of wanting something to look a certain way.
I'm no engineer, so it's not my place to question Jim's design, but I'm curious why every other world class sports car does not shares the same specs? Does the wheel base really have to, for example, absolutely be 95"? Would increasing the wheelbase 3% to around 97-98" really be a detriment to handling? Or is it a production issue? Blowing up the entire Rodney design by 3% would increase the overall height by almost inch and a half which, in the context of headroom of a car, is huge. The same would apply to any of the other designs as well, and really let the artists keep the proportions that want, but make it easier to achieve WC status.
My other fav is Shawn's design and, while it seems to be even less WC, a little loosening of the strict requirements (given that Shawn appears unwilling or not have the time to tweak his design) would allow it to get that much closer. If so, maybe Shawn would then make the effort to tweak it.
