I’m currently hosting a competition on 99designs to find the best design for the cover of Ismark: The Marked Boy, and it is not easy to pick from all those wonderfully talented artists and designers. Some of them really put their hearts into this and being a nice guy, I hate to pick someone and disappoint a truly talented person. Anyway, if you want to take a look, here is a link to the contest:
