Aw, you draw lovely ponies. Don't worry. Your shading style fits them really well, so they turn out great. That said, your style does leak in a lot, but it makes them look better in my opinion. xD Adds more life.
I love your work, I love ponies, and I love this pic, but I must admit I'm glad that you don't do too much pony art. I've seen many amazing artists jump this bandwagon and at this point its just getting old :/
This is something I must agree with! I know a few really talented artists who have switched to drawing NOTHING but ponies, and it's so disappointing. One of them even admitted that they're only doing it for the popularity :'''')
It must be a rough crossroads indeed... I mean on one hand I'm sure they're enjoying the attention, but on the other they've lost sight of why they even started their artistic endeavor (generally speaking).
