Sorry Scootaloo, I'm afraid you're stuck with the lame cutie mark the show's creators have given you.

This was obviously drawn in Paint or something, but I kinda like this for some reason. The rear leg anatomy is kinda wonky but the goofy smile is adorable. Of course, the quality makes sense if you assume this is Scoot's fantasy sequence.

Not a top contender but not terrible either.

One day she will have two pairs of wings instead of one? M.A. Larson striked again. He has gone beyond alicornication, we have to stop this madness. Everyone, hide your waifu, nopony is safe.

Jokes aside, this is very simple both in the technique and what it represents. While this doesn't help to gain points, the consistency definitely plays in its favor. Moreover, her goofy smile makes me smile too. That simplicity pleases me in a way. So clearly not a top tier but not a bottom tier.

This works as a rendition of a child’s fantasy drawing. There’s not much more I can say about it.

I can see this being something Scoots doodled and tacked up on a dream board. Which makes it really sad, despite the ostensibly cheery nature of the piece.

This is like that one artist on Derby brew whose name I can't remember so I guess that's not a really useful statement.

I second >>Rao's analysis here.

10/10 MS Paints.

This was my choice for the entry that I didn't finish, just in case the artist is curious. I was moved to write something attempting to link the colorful surface and the depressing undertone to a final, happy ending. Which I made decent progress on, and had I started it a day earlier I'd have finished with time to spare. But, alas.
