Marshmallow!

I really like this color scheme, for some reason. I think because of the gradient on his hair, going from deep blue into teals and yellows. Nice drawing!

It looks great, how do you do flat drawings that well? Any tips?

Sure! Here are some of the things I do with this kind of drawings!

1. Keep shading to a minimal. The simplistic (as the name suggests) style is meant to keep things simple and 2D looking. 
2. Outline only when you need to, but with a shape. It's best to use different colours to show the shape and to use other shapes to define two separate shapes if they are the same colour instead of a dark line eg. the hoof and his face. Also use colours that are darker but close to the shape's colour when you are defining it.
3. Use a vector program! It is much easier to create shapes and straight edges on a vector program. I use Inkscape for all of my drawings because it's free and it is easy to use. It also goes well with drawings that are "MLP" styled.

That's about it!
