I can sometimes guess who the artist is in some challenges. Especially the artist who have a distinctive style, but there are still sometimes that I'm completely surprised. Do I let the fact that I might know the artist color who I vote for? Absolutely not!!! I judge the icons on several factors; 1.) Quality... are they well made, with no noticeable flaws. 2.) Coloring 3.) Cropping and 4.) My personal taste.....this usually means the icon I can't keep my eyes off. Who made the icon has nothing to do with my vote.
