The concern on Rarity's face is amazing. The shadowing is very consistent and smooth. The color you used for the back ground really adds depth without being so over bearing, or distracting the eye nor is it to bland or boring. The concept is hilarious. Over all exceptionally well done, and well thought out. the only thing that really pokes out at me is the sandwich derpy is holding. With all the detail put into the piece it seems a little flat compared to the rest of piece. its part of your style to make colors and texture smooth, but adding a rougher texture to objects in the foreground to make it really detailed.
