Who knows? Just upload and see how they go

It's difficult to decide exactly what buyers want so the best bet is give them the choice.
I don't reject photos on subject matter as long as they are intrisically good photos. Let the buyers decide what they want is my feeling.

This is just one of the reasons I believe SS works so well for the photographers. In most cases if the image is technically correct they will accept it, except of course for flowers. I think they get so many of them at times they have to be a bit stricter on what they accept. I understand being one who takes and submits many flower images. I just submit them and let them decide which ones they think they can use.
