Rarity and Twilight! Still very much a WIP.

It's my very first multi pony picture! It's by no means done or even close, but I've spent a good amount of time on it and would like some advice before proceeding further. So, here it is! http://www.imgur.com/0pBA7.jpg

EDIT* I made some changes. Here's the new picture, on a scanner instead of crappy phone cam too!
