Fluttershy

The first thing I notice about this art is that it's rather dead looking. Fluttershy looks kinda of sickly because of the pallor of her skin. However, the proportion in this is really great! The pony Fluttershy has a really good measurements and a complicated angle; I think you puled it off really well. The coloring in this is really good and smooth. It blends nicely together. The coloring of her skin looks gray-ish and takes some of the life out of the drawing. You should add a little more pink/red to her skin so she looks more cheerful!

The background of this is really lovely and I love the out-of-focus butterflies on the edges. The sky should be a little more blue so it looks a little brighter. I think you've got a great piece, it just needs a little more color and saturation <img class="avatar" src="a.deviantart.net/avatars/w/i/w…" alt="" title="wink-plz" /> you have a fantastic sense of proportion, just work a little more on hues and saturations!
