Hey Victor, I am really happy that you contributed to the 1UP cause. However, I cannot accept this yet because it has not as much work in it as all the others. You have used a very simple pixel art for the bird. It consists only out of a very rough outline. The color gradient ignores the pixels and jumps over them. Try to use one color per pixel. And the 1UP logo is out of style because it is entirely rounded.
I think you should try to improve this to keep up the high quality on Utopian.
