New sketch, "Force of Nature"

Worked on this sketch on Wednesday night, and traced it in Illustrator to post in my shop the same evening :) inspired by Pearl Jam's "Force of Nature", and also the concept of serving as a beacon.

You can see my sketch progression in these two shots:

I am offering it as prints using two color combinations - red/orange and green/blue. I'm considering making a shirt of this design, just because I think it would be rather striking on a black shirt.

Which color do you like best?
