Character Help

Working on developing my first actual character looking for tips to help make the character look a little more menacing. Obviously still have a lot more work to do but would love the advice.

Looks great! As far as it having look more menacing, I would say the facial expression is a big key. I would frown the eyebrows and center brow down and bring the mouth into more of a yelling open mouth type expression. Other than that, love the character!

Thanks for the help
