As I mentioned on another pic of yours, photos of the fronts score better. Lots of things here, maybe I can help: White is a pain to paint. How to make whiter white highlights? How to make dark white? the background does not help either. It is too busy for the mini. choose a plain gray card or a blue white fade. Finally, the pic HAS to be in focus. We cannot judge your skills from a blurry pic. I am not picking on you here, all of these you can correct. Paint more, post more.
