It was done so very often after the relevant episode, but now, after some time since its airing, it feels good again. Love the curve of the wings and the detail in their irises here. Also, the positioning of Dash's hooves. Well done!
Don't get me wrong, I don't mean it's you who's overdoing it. I simply meant that the theme was very frequently used after Sleepless in Ponyville. Since then it subsided, however, and seeing it now feels a lot better than seeing it then. Forgot to mention that I like the shading around the edges of the feathers and bodies in general, as well as the soft appearance of the clouds.
