I personally preferred the other one, I think it was feminine enough because Rainbow Dash ISN'T feminine, but I suppose this one would appeal more to others who prefer a more stereotyped gender. Still, good work, I'm especially liking the belt, nice touch. Your cloth work is beautifully rendered.
This is really, really well done. I like the humanized versions, but more often than their pony features feels forced on a human body. These pictures are the cases which counter-balance all those forced attempts. You know you'll have to do more. Scootaloo is the only missing CMC and I would love to see a Derpy, elthough I know it's not my business making requests/wishes.
