Oh, wow, this is just outstanding!! O_O Something about the atmosphere of this picture that surrounds the dragon is both uplifting and idyllic, just seeping with a sort of serenity this dragon might be feeling. The contrast of the colours is wonderfully executed, too, sufficing to give it dimension, and yet despite the odd colour clash, it works out superbly! And the dragon itself; just beautiful. I love its pose, particularly with the wings where it appears to be dragging the clouds along with the tips of the outer fingers. The details were very well shaded, too, and almost makes it look as though it were popping out of the image, even if the overall composition is a little abstract.
Anyway, sorry for the long comment, but I thought I'd express myself. I could really learn from the details of this wonderful piece! ^_^ (Okay, I'll be quiet, now. XD )
