Iris Re-Design

Hello there! I was thinking of redoing Iris sprite, since I'm not completely happy with how it came out. And I thought, since I'm starting to have some patron that show interest in the game, let's ask them!

What would you change? Re-draw her face, or the entire sprite? As of now, it's not very defined as a character. Would you suggest some characteristics, both physical and psycologycal, that make her unique? 

Comment wathever you think, and I'll take it into consideration to re-design (or not) this character.

Thank you all!

Kisses :)
