Battle of Ostrovno in 1812, 1845 by Albrecht, Adam

I was wondering about that myself. I think it is a color thing. I've always been able to see colors really well. I have a harder time when the tones are very similar. And there are times when I'm "in the zone" and everything just clicks. I don't get those times very often though. :) Hugs, Anj

So intricate, how do you complete so fast?
