Dashing Dash

I had a little bit of free time and I decided to go ahead and play around with my new Cintiq pen by coloring the Pint Pony sketch I did of Rainbow Dash. I was gonna add shading but I figured it would stand the way it is just fine. That, and I'm somewhat debating on whether or not this could be a design/image for a t-shirt if I add something to it... what do you guys think? O:

Other than that though I don't have much to say about this, so I hope you guys enjoy Rainbow in all of her rainbow glory! x3
