Porsche, but with Ponies! (FIXED AT LAST!)

My first real attempt at a vector!

I'm not a big fan of Porsche, but their logo is really nice and shows Porsche's origins. You'll probably notice some big differences between the actual logo and this one, and that's because I took some artistic liberties, like altering the flag on the opposite sides. The colors are actually part of Luna's and Celestia's coat, which may look a tad odd when right next to each other.

Any constructive criticism and feedback also appreciated!

EDIT: I noticed that the vector's edges become jagged, probably because I made it in PS, but I fixed it by importing it to Ponyscape & exporting as a PNG. I've been wondering how to get that problem fixed for months.
