Samples Rejected

[beeks7631]

I recently started trying to upload some of my work to Adobe and they were rejected it and I don't understand why. The reason why said that I should post on this forum to get an answer. Can someone tell me why this would have been rejected?

                                                

"Thanks for giving us the chance to consider your image. Unfortunately, during our review we found that it contains one or more technical issues, so we can't accept it into our collection."

That was the response I got but I don't understand what it could be. If someone could help me out I would appreciate it. 

Thanks

Please show us the defective pictures so that we can tell you why they were rejected.

Now I see. The folder is the submited drawing. The only reason I see is that the gradient isn't smooth. At least on my monitor.

Pixel graphics or vector? What I see is that the borders are not clean. What tool did you use?
