What was the rejection reason?
The mood of the shot is good but I see here a bit too dark, and too much noise. Were you shooting high ISO?
First of all reedit from scratch, check the levels carefully and get it to 1024.
Looks level too me taking the middle verticals as reference but I guess slightly too much contrast, and a bit soft, then I think it should be ok.
But I'm no screener and maybe they will find it too dark or lacking depth of field.
