If you just need to learn rigging this should be good enough, or just look at wries or use it in a game. Its free for what ever you want, as long as I have credit, this however modeled for Takran Online, but my content is not binding to it.
Just a few points, thats just my point of view of course…
I don’t get your aproach for the eyes. Of course we can add movement later. But, in my opinion this “extra” polys would be better used for some detail for feet and hands.
The texture for the ear could be a little more “soft”.
I need to test your nice aproach for the arm articulation (middle). I usually spent 3 complete edge loops to make that.
Btw, this is just my opinions. The model rocks! Congratulations. Thanks for sharing this one.
