If you cannot determine from this picture I am a really big fan of the MLP Friendship is Magic series. This is a color pencil piece I did a year ago on something of a whim. My main concern was trying to match the digital colors of TV series with my color pencil, marker and technical pen style. Especially since I did not want to accidentally create non-photo blue in the process. Overall I am quite happy with the results.
No this is not canon to the show. It is not even canon to the dreams I have about Equestria, and in all honesty Rainbow Dash is probably the last pony in the world that needs a window rattling, flame belching, chrome plated road rocket. Which is exactly why she would want one!
