I also entered a monster contest at Redbubble.com, which is a site where you can buy artist's work on various items like ipod cases, t-shirts etc. This was the image I submitted to the contest.
I had a lot of fun and learned a lot from doing this one. I had to start it over because the original composition and design were pretty bad and thus only had 3 days to complete it. That's a new record for me.
Sadly, this image did not make it to the finals of the contest to be voted on for the big prize but I can't be mad at him. He got a lot of attention for me being very new to the online store and I hope to get more in the future.
