It's been said already, but the waves are amazing: and to my mind, using a fractal texture to create them seems like genius. I love the way the waves all seem to be descending upon Danaid's Basin. The rocky crags and cliffs around the Titans' Prison and Shades' Land are also incredible.

The main problem I see with the map is in the labels, especially River Phlegeton (fire). I'm not particularly good at labels myself, but the way that label twists so much looks wrong, to me.

Also, my knowledge of Greek myth is a bit hazy these days, but wasn't Charon's ferry meant to take souls across the Styx?
