Wows! This looks cool, it surely caught my eye. To start it off, I like that texture-ish stuff in the background and I also happen to like the blue splatters everywhere. Rainbow Dash's expression is marvelous, it also fits her personality. Very original, except for the fact that I've seen a lot of Rainbow Dash stuff so there's not much I can say about totally being original :/ oh well. As good as it is though, there are some things that you can improve on. The splatters are good, but the majority of her body is hidden behind them. And also, I know the white line around Rainbow Dash is to make her pop out of the image, but when all of the dark colors suddenly mash into white, it's...blinding. I don't know about anyone else, but the white is sudden considering that there's so much dark color around it. Next time, instead of using white, I think you should darken the color around her, and that won't be a problem because she is light colored. So yea...that's my advice! ^^ Not much but hope it helps!
