Rejected AI Image

Hello all,

I'm new to the stock uploading world. I was curious if someone can tell me where I'm going wrong with this image. I myself thought it looked great but I am wondering if maybe there was problem when the file was uploaded?

Can any of you critique this image and tell me why it might have been rejected? I want to make sure that the images I uploaded meet adobe's requirements but also don't want to spend time uploading if it might be rejected. 

Thank you!

Here's the image:
