Hey, that's a great idea - I mean, you're sure that you can do better - so come on, show us how a real badass get things done, just imagine - you're going to make your own game, which will be better then this, obviously, weekly updates, new girl every month, no bugs at all, all Oni patrons will abandon their deceitful overlord for a new Porn Michaelangelo, NSWF-Extraordinaire - sounds like a dream, I do wonder why didn't you thought of that before, that's genius.
And, as an artist IRL myself, I can confirm that what Tewinter said is true - with practice and learning on your mistakes you are bound to succeed, talents are lies and drawing is enjoyable and easy to learn, the first steps are the scariest.
So nothing really stops you at this point - i mean, there is one itsy little thing called coding, but I'm sure it can't be that tough, I mean, if a lazy ass Oni can do it, you'll won't have any problems at all. So go on, get right on it - this site deserves a hero of your caliber.
