So many people saw my very quick sketch of this and wanted to see it coloured, soooo, here it is. I was too lazy to do it myself, but fortunately there were a few volunteers so I grabbed one and made them do it xD

This one was coloured by jaxa. So hopefully that'll be enough to satisfy you guys x3 I think he did pretty good, myself!
