Rhino Logo - unused concept

I took a skl class about creating sports logos from @Fraser Davidson just for fun, and now I will be creating a whole series of these tuff guys.
It is a great class, I enjoyed it very much and recommend definitely!
I was more into elegant and softer kind of style ever since I started designing and thought I needed to expand my style. Plus, I think that no matter how experienced designer is, learning new stuff is mandatory and after all, so refreshing. So, what do you think? :-)
