Polar Opposites

Ah, finally done, I spent quite some time today and made sure i will get this one finished, what's the story behind it? Well Rainbow Dash wanted to check her top speed with additional weight, and Fluttershy has the (doubtful) honor to play the part xD

Those two share really cool dynamic, despite being two totally oposite personalities it's hard to think about one without another, it's always fun to see them interacting toward each other

PS don't worry, Fluttershy will have her "payback"
