your art is awesome!, but you can't put your signature if you are going to use it for the contest!!! , because it's against the rules! so you should edit your deviation and reupload it to make it works :0
well...it's not just in one day...actually it took me 2-3days to finish this pic.In the frist day I need to think about how to creat a character(PS:I play many games,which always give me inspiration.)Then I do the sketch,once I was satisfied with the sketch,I go on finishing the pic.That's the whole process.
