The first tutorial I've seen...
...that makes me feel like I can actually draw well. You've made drawing anime characters...well, the challenge of it got through all right, but previous tutorials kind of lost me because it still seemed complicated. But this tutorial actually makes me want to buy Adobe Creative Suite right now so I can get to work.
I knocked off a couple of points for sound because I wasn't terribly fond of the music you played in the credits, but that's relatively negligible. Other than that...Thank you. THANK YOU. A million times, thank you!
P.S. - Your Metroid thing looks pretty groovy.
