Well, I am going to bed way past my bedtime, but this is the result of two evenings' work:
Click to make bigger, etc.
It's a painting of the first Dr. Wily Castle boss from Megaman 2. That dragon scared the crap out of me as a kid, the way he came out of nowhere while you were making very precarious jumps through the end of the level. He is badass for taking up just about half the screen, and for being one of the most detailed NES sprites ever. I will post the reference screen shot later for those not in the know.
I like this one a bit better than the Snake Man one. I'm not perfectly happy with the dragon, but I figure I had to end the madness. It was taxing.
I might continue the Megaman trend and do the Yellow Devil from Megaman 1 next.
