Hello, I’ve been drawing furries for a little while now and this is my most recent pair of studies (their respective references are the next two photos). I really like their eyes and overall softness but they look sort of blank to me if that makes sense. What areas should I focus on improving to fix this?

Thank you for any constructive criticism/advice!
