Cute, and very well drawn and colored, interesting eye texture you got their how the pupils merged in with the iris I believe what's it called the hairs simple enough with just the right amount of detail to have that cartoony effect to it. Though I have to say the yellow colt (think that's what he is) right leg is slightly not contrasted enough, should be of a darker shade not a lighter one if you ask my opinion, but over all the picture is really great and could be a very unique background for some pony.
Summed up great drawing. ^^
Thanks derpi ♥
