I'm unsure if this is too busy to work as an emote. I shrank it to 120px wide and I could still see it fine, but that could be because I spent so much time looking at it.
As far as usage goes, I think this falls into acceptable usage as per the authors FAQ. The author is homriette, and they have in their FAQ the following that, as this is fan art, allows (from my reading) it to be used as an emote on this site:
As icon on social media profile and that, I don’t mind. You don’t have to give credit either, is recommended but not mandatory, as long as you are not claiming the art/characters as yours of course.
Headers are fine~too , but be careful, no headers for accounts that are business or the like. Fanart is preferred than personal art in this.
