Every self-respecting sports logo artist should have a wildcat in their stock folder (also, bulldog, eagle, tiger, etc). Its a very common mascot and therefore difficult to create in a unique way.
This concept is basically a Northwestern Wildcat. but the design would meld easily into any wildcat brand.
The only feature that I'm unsure of is which "light area" color works best (white, light purple, lighter purple).
White Light Purple
Lighter Purple White with Light Purple Border
I kinda feel like the white is too harsh and the light purple blends too much, so I'm leaning towards the lighter purple.
