This is a gift vector for a brony friend on Google+. He had a really shitty birthday this year, and because I felt bad for the guy (having a shitty birthday myself this year), I wanted to make up for it by making him a gift vector, and he requested Rainbow Dash. I gave it to him a while ago actually, when I finished it, but I completely derped on posting it here until now.
To be honest, i've been waiting to do a Rainbow Dash vector for the longest time. For some reason I like the idea of having to do all those colors separately for the mane and the tail, where most people seem to not like doing that. I dunno, Rainbow Dash seems to be a really rare case where she has a rainbow color scheme, and yet none of the colors make her overly bright or garish to look at in the least. She's very soothing to look at, actually, with a light blue coat she's just very easy on the eyes.
I loved making this vector, probably more than any other vector i've made so far, and i'm glad that my brony friend likes it.
