This is just a study in perspective and lighting effects. All elements were created manually in The GIMP 2.2.11. I was playing around with various lighting methods, as well as the use of noise to create soil & cloud textures. Also played around with creating a steel/metallic frame using multiple gradients. To my surprise, a keeper emerged! Too bad I started it smaller than a normal hi-res pic... Anyway, here's a study... Worth developing further into a full scale pic? Thoughts?
