Sorry I didn't reply sooner, I wasn't around for months. Wow, I didn't even know DA told artists who bought their articles.
The puzzle that I bought (Sunrise) was awesome, I really liked it. We (me+SO) were afraid how it would turn out, complexity-wise, but it was OK. I still have eyes for some of your graphics, but many are too complex for puzzles, I think. Still, great stuff, keep it up!
NB I'm not an artist. Not sure if that makes my opinions more or less relevant
