Sorry I'm incredibly late posting on this... but
How am I supposed to give a critique when there isn't really anyhing to critique? <---- ultimate compliment xD
I had to play search and find but, i found something that is better on Bowser than StarStruck: eyebands. And that is usually such a trivial thing in the first place.
I think Bowser is one of those small bucks that we all adore because they are small. Because of that, though, his bone just isn't quite up to par in proportion, especially compared to StarStruck.
StarStruck has very striking rufus and just has an edge over Bowser in pretty much everything because of his better color. It gives him a greater effect of mass, to quote the book on it. His excellent type is certainly the basis of it, but the color gives him the edge. The only way he could improve besides the eye circles is to shave a couple of hairs off of that loin length.
