Please help, what is the reasons for the hard rejected of this item?

I send this item to envato graphicriver but has been hard rejected
can you tell me about the reasons for this rejection

hi well i rather like it but quite frankly u have some issues as regard to shadows and thus too realism indeed. Here choosing busty women for the preview is just a way to put yourself into trouble and to offer an opportunity for people to add other reasons to reject your work, in the end … here, the policy is very puritan and using something else than nuns is not welcome lol
