Ok, so here are the unofficial "rules" (more like suggestions) for the Advent Sketch Mare-a-thon:
Do a 15-30 minute pony sketch or speed-painting or what have you per day 'til christmas. It can be any pony you choose, doing whatever you want, wherever you want. The point is to keep it quick and simple, and to try to improve and have fun.
Upload it to DeviantART and name the submission "Advent Sketch Mare-a-thon, December 1st" and so forth up until christmas.
If you decide to join in on the fun, let me know with a comment! ...If you want to that is.
Have fun!
My submissions:
December 1st: Rarity singing in the shower.
December 2nd: Flut
