I love the contrast between the flower's colour and the black of the background. A good choice of surface, as it reflects the flower well, without detracting from it. However, I have to agree with *bleachedMIND; A higher resolution (even 800*800) would be good for this image.
The resolution for the image is 3000x3000 because I set it to print but I only display it at say 400x400 or 600x600, but I completely agree. Haha! Yes yes, dA's resizing is pretty crappy - it's limiting because of these reasons. I've had people say in the past they can't see the whole image because it's too big XD
