I came up with a quick, simple and fun exercise to flex your drawing muscles and your drawing memory before doing a comission or a big project. Take a piece of paper, draw between three to five random circles, and make one drawing into each one of them. In my case, I filled those circles with pony. Twilight Sparkle in particular.
Because she's the most interesting character of the entire series.
Enjoy your multifaceted Twilight!
You gotta love those old school over-the-top facial expressions.
