Sooo… this one requires a bit of explanation:

So I'm a student in a Graphics Design class in High School,
Yes… I'm in High School.
Everyone was required to do some simple Popsicle design, most likely based off some character you've seen a show or a movie. After seeing a bunch of really bad ones, I decided,
"Hey, I could make this look AMAZING if I made it into a pony",
so I chose Pinkie Pie.

My Reasons for choosing Pinkie are :
1) Her hair is REALLY fun and actually decently complex.
2) It could actually make sense in canon… I mean seriously think about it.
3) PINK!!!!

Also we were expected to print these out onto glossy paper for display, so backgrounds were highly recommended. Which explains why there is one.

If someone wants me to, I'll put up a vector for it, but I fail to see a reason for why you'd need a vector of this.
