I resubmitting the piece because it was in the queue for a lot of days and I didn't receive any messsge of the error, so now that I know I will fix it (and yes I see it and it was for the automatic glow, I will make it by hand)
Resubmitting work that was previous not accepted without making any changes will not help it get accepted.
I think case, the automatic glow is the problem, since it creates a tonne of colours outside of your control.
When your work i stuck on the queue for a while, resubmitting will often only make it stay even longer, since you'll lose the votes you had on it D8
