Great start to the challenge, and great initial design. The silhouette is really strong. I can't at all tell which side your character is on, light or dark. The left side of the image looks like light, the right side, darkness. The description sounds like light (although I only see one main character here: If your warrior is named Raksha, then who are Fluff and Crunch?) Anyhow, that probably doesn't matter, as the judges will be looking at the image, not the description... but better make it really clear from the image which side he or she fights for!
Anyhow, great start, wonderful design work so far, good luck with it!
