This is a great piece of fan art you've got here! Great value in the colors, nice job at the shadows and lights, and a fantastic feel, as well. It also helps that I just plain like the designs of Vinyl Scratch and Octavia in the first place. I've never really thought about which background ponies are my favorites, but these two are probably somewhere up there. I would definitely enjoy seeing these two together in the show at some point, since they just look so great together and all. Amazing job, overall.
