Rejected for similar images but these are the only two images like this ever submitted.

I submitted the two images attached that are photoshop illustrations rather than photographs. These are the only illustrations I have ever submitted. I don't understand why they were rejected for similar file already submitted. Both were rejected and there are no other images that I submitted that are illustrations. Was hoping for a critique on the quality of the art and if its appropriate to Adobe standards. Puzzled because the similar images notice is confusing. Similar to what? Would like to create more art like this but am not sure if I am submitting correctly or if the work is something Adobe would be interested in. Please let me know so I don't try to submit the wrong kind of work again. Thanks!!!
