I tried submitting my entry on the gallery but I keep getting an error message (CLOSED)

Its few minutes till deadline, tried submitting my entry on the gallery but I keep getting an error message, so I will post it here.

Spent a long time on this and aint no way I aint posting it. 

can't seem to post images here either... damn.

I know it's too late to get the entry submitted now, but I'd like to help figure out what caused the problem.
