The only thing I really notice is that her eye model and eyelashes use Twilight Sparkle's/Spitfire's/Fleetfoot's general model, which has the point at the nose and curled upper and lower eyelashes, rather than the elliptical eyes with straight eyelashes that Roseluck has (as well as most other mares) which also lack lower eyelashes, like in one of your other works . Otherwise, from immediate view, everything else looks fine to me.
