I was a contestant and the only thing that I've think about some of the works is that they are pretty confusing, some colours and lines are weird, faces and things like that are pretty awkard. I don't know, just my opinion.
I liked some of your choices but not all of em. I was definitely a fan of the weird and unconventional art styles that obviously must have taken a lot of time and work to produce. However, in my opinion there were some other entries there which might not have relatively taken as much time and effort to complete, but the the finished product and quality of those entries were just better.
Some of these works you chose are absolutely weird. Distortions, colors that don't match... Some are not even clear! I really think that the hand-made jobs worked better than those ones who won. Digital art can be good, but in this case, just a few of your choices are great works.
