I've seen dozens of vectored art of the ponies that matches the artwork of the characters themselves posted by a few others, and I was like "there's no way they can be that good!" Then I noticed they gave credit to the owners of the show which are of course Lauren Faust and Hasbro. Because it's clear they didn't draw the characters originally. Basically, if you post artwork you didn't make yourself, it's a wise idea to give credit to the person or people who made it first. If you look at some of my drawings on my profile page, they have "copyright 2014 LunaFan88". The copyright is actually a c in a circle. That means they were drawn by me, and anyone who posts artwork that is mine has to give me credit, or they face what is called "copyright infringement". It's a serious thing when people claim something is theirs/or they made it when they didn't. I hope you still know that MLP:FiM was created by Lauren Faust and the show itself is owned by Hasbro. If you did make this, I'm curious to know how you did that.
