Someone made a felinoid, and I was inspired to make one too.  

I have to say that I think that you are manipulating the colors well. The way that you have the tone changes accentuate the muscle is very clear.

I feel, that your characters have a sort of deer in the headlights kind of expression. This is due to the severe round shape of the eyes. This can be remedied by adding an eyelid arch touching the iris/pigment of the eye.

Thanks for sharing. I can see that you have a lot of ambition. Keep it up!

This one has more realistic eyes.
