Heh, I wanted to avoid having to use this one because I wanted to compete with it myself XD
Since the resolution is so high, and the imagery itself is so detailed, theres a lot of massive potential in this one. Ill will be severely disappointed if I see some really generic uses of it, because there's just so many areas that could be sampled and recomposited. You could really go an enormous distance from the original, and I look forward to seeing what other people can find in it. I chose Arthas for the same reasons.
Usually I find the premise for most artists is to either create something that looks cool, or create something with inherent thought. Its much more challenging and fun to do both ^_^
