Daily Contest Rejection UI-Fix

For the daily contests it would probably be helpful if the rejection message was on a different colour background, so as to be easier to spot, and perhaps even accompanied by a notification. For me it would've been particularly relevant, since I did try to check my images but apparently missed one of them (a tree) being miscategorized as explicit female nudity and so missing out on the contest. Anyways, best of luck and take care!
