Well first of, this is a very pretty peice.I love the colors you chose for the backround, the colors on swiligt are decent. The cutie mark is good and the mane is spot on.
Now with the negitives ;w; sorry if I am rude or something this is only in my opinion, the hoofs are a little skinny they need too come out more. The rear is a little umm..big, and kind of wobbaly.The eyes need too be a little bigger, and the snout is a little off, try too make it les coming out. The last thing is the neck its a little too straight it needs too be like a chest and a neck and not just a neck. I love this peice!
