I'm not from Dim team, but i don't understand your disappointment... Why should they give you more? Because you think that your art was better than others? Maybe they thinks that all of your works was average? I think 5000 from 1000-25000 is pretty good. Maybe they wanted more single good-quality artworks instead of 100 less-quality? I'm not judging your artworks(in fact right now i have turned off pictures in my chrome, so i'm 100% objective). They just didn't wanted a situation, where every single people send them 200 crappy images made in paint in 10 second. I'm not telling, that you did that, maybe all of your works took you 1 hour each, but you seems disappointed by the fact, that you've sent them 25, and got only 5000. I don't think that was their point(to have as much pictures as they can)...
