As reflected in the SVG filename, this is the fifth commission I did for Starponys, featuring Rainbowfire/Rainbowbarf/Flying Colours puking a rainbow. My first draft had a smooth rainbow into a cloud, which was rejected as "not vomit-like enough". I therefore added several crenellations and was surprised myself at the effect. I made another version with an alternate cutie mark.
