Lower part of front is rather boring, while back/side part is pretty crowded, either remove a bit of those tribals from back/side or add something on the front.
Also, back looks bad because of the big tribal there, cut it out somewhere so it's not like a stick there.
But overall it's nice compared to stuff i usually see here, even though eyes are horribly generic.
Next time try to make it asymmetric and see how it turns out ;p
