Wowzers ... This is amazing John. It looks like I'm face to face with Satan himself .... kinda spooky. Excellent flame work & I promise I will be real good from now on ... LOL! Looks great on the desktop also ... he, he.
I guess the color red has as association with hell and the devil. It is a seductive, hot, steamy, passionate color, but always one of my favorites. Also see a fractal about this same theme by bfrank. It too has a red and green theme. I think yours is more scary in the half at the bottom where it looks like a huge mouth with its uvula hanging down. I don't want to go in there!
