Why not accepted?

Hi, its the basic thing to understand that none of the commercial sites who trade stock images and illustrations, allow self promotion through logos and any kind of marks which points to something other than its concept. Beautiful creative, but those six dots at the bottom makes no sense at there. If you can justify the usage of that, maybe they'll re-consider it again. As from the first look its hardly understandable about its positioning. Its not giving any value addition on balancing the total art. Visually its disturbing. Maybe you can add someother elements with it to balance it to look better & more creatively appealing. All the best. Great art. Good uusage of colors and the wavy flow of color separation. 

Now that @Test Screen Name pointed it out, I would remove the dots as well. I find it distracting!! The eye is drawn to this!

I think the pattern of dots also seems likely to be viewed as a fault. It serves no obvious artistic purpose in this interesting work. 

Hello,

Don't upload anything with logos, watermarks, etc...

The logo must be removed.
