Ethereal...
A spectacular use of desaturated yellows with the blues. Gives it a really transcendent feel. I could argue that the middle seems to have a lot of white, and that's a little disappointing considering the rest, but the rest of the picture more than makes up for what is already a lame complaint.
Did it in PS? I don't think I'll ever be able to create work of this caliber digitally...
In any case, a wonderous piece. Keep it up!
