I saw this when it was still new and I was not yet in the fandom, and ever since I've become a pegasister and Rainbow Dash has become my personal favorite, I've been searching like crazy for this. I'm so glad I finally found it! You have no idea how much of an inpiration this was to me!
This is one of the most amazing Rainbow Dash pieces I've ever seen. <3 She looks somewhat like a goddess! lol I love the lightning bolt (her cutie mark) coming out from the cloud she's standing on. Seriously, the color and artistry is just amazing here.
