UPDATE: Changed my grammar mistakes!
Tom Fischbach's tutorial on digitigrade legs, that I use frequently:
This is kind of a "How I Draw" deal than an anatomy deal XD
But honestly, everyone draws their own way, so I view this as a general guide that you can take tips from. If you're really serious about improving your anatomy, get to know the muscles and tendons and other such junk of the human body (or any animal body you're drawing).
As stated in the drawing, I don't need any credit if you use this. If you so chose to, I'd certainly not object XD But more than anything I just wanted to share with y'all this, and I hope it helps!
OH! I would be upset if you decided to steal this and claim it was your tutorial. But that goes for all my art, so that's sort of a given. Please don't steal! >W<
