Eternal inner senshi

The inner senshi in their eternal outfits, only seen in the manga, from Sailor Moon. I have some regrets about this one, for one thing I think that I made venus eyes a bit too big and too close together. I wonder if not the sketch I made before this one actually turned out a bit better then the finished product.

Anyway, I would love for you to give me some tips on how to improve so all comments are most welcome
