Hey there, light side character!
My main critique so far is that there should be more round skull behind her horns. It would make her face more believable and also give you more space opportunity for horns/headdress costume.
When you get to color, I think it would be cool to see some of the "fire" idea on the pattern of her scales as well.
Will there be some other monks behind her in the final illustration? I think that light-side leaders do well with having lots of companions to emphasize their skills.
Keep going!
