I picked a frame from , traced and edited it a bit in Inkscape, animated and exported it's frames with Anigen and assembled them with APNGAsm.

Color guides: Scoot and ''universal [pony] colors'' (though I edited her tongue color, official screencaps seem to have done it too) and wing reference from >>1046758

If I offered this as a YCH what would be a fair price? Or should I create an account on one of those YCH auction sites?

Also available as a Rainmeter skin so she can preen happily on your PC :D

Thank you so much to Byte[] for fixing a bug in libmagic that wasn't allowing me to upload this SVG!
