“I’ve seen a few of these before so I’ve decided to make one myself. I am no artist, so I’ve used what skills I have in Photoshop to make this.
 
The process is simple, draw MLP characters in the 20 emotions that I have listed. They can be their normal pony selves, Anthro, Equestria Girls look, or even R64. I just ask no OC’s. You can use backgrounds, props, even the upper bodies of the ponies instead of just the faces if you wish, don’t limit yourself. You can sketch it, draw it, vector it, whatever style you want.
 
Reason I am doing this is just to give artists a chance to practice their stuff. If you complete it, send it to me and I’ll post for others to see. Who knows, maybe somebody will be impressed with your style and commission you.”
