I just uploaded my first tutorial stream and packet to Gumroad! If you want to learn more about Pony Anatomy and especially Pony Expressions (and the basics of expressions for all creatures, really!), then you're in luck: the price starts at FREE! Go pick it up here!
Note: Contains strong language.
Double-note: The success of this video determines whether or not I'll do more -- so definitely check it out if you want more tutorial videos on different subjects!
