I'm trying to work on this image and I want to get rid of the grey part but continue on the blue and black parts. The attatched shows what I mean, and the link sends you to the full size image. Would you prefer vanishing point? It's okay if you try to do this yourself, but I want to know how to do it, so if you succeed, please do share everything!
