hi sc, do you mean a light gray background like that? this is version 1 but also got rejected by same reason.
just try to understand what a buyer really needs..
i can make it whiter but i find it easier for a buyer if they want real isolated and yet they may need a natural background.
I think you are still missing the point - it's too close to looking like you wanted to isolate it but failed. Either it needs to be all pure white
or all close to a light gray. Right now it doesn't look like a natural background.
