You and your shiny ponies. Keep them up, they're good. The only thing I find strange about this picture is the lack of a cutie mark. I love her shiny coat and her bodyshape here. Beautiful work with making her hair extra-reflective with those white lines, too. I really like the additional volume and length it has here, too. And those wings are beautifully rendered. Finally, the magic glow looks pleasant and is nice to see, and those closed eyes and peaceful expression are gorgeous. Twilight herself is. As for the background, nice addition of the white lines to the purple reflections on the clouds, makes for a good impression of a bright light. Well done!
