IMO this one and Vinyl have been a bit too humanoid in appearance with how they're standing on two hooves. They're much more like anthros than ponies at this point. The Twilight artwork managed to pull off the standing on two hooves thing since it had a lot more going on with the wings and the bow&arrow, and, IMO, the Trixie, Starlight, RD, and AJ have been the epitome of your work on the Zodiac pony gold cloths.





A couple good examples of standing on hind hooves from the show itself are Twiddly Twang in Luna Eclipsed/Apple Family Reunion and Daring Do in her debut episode in S2. They never fully stand upright, but at a slight angle, sort of like an actual horse rearing up, and when they do stand fully upright, they usually support themselves on another object, like how Octavia herself holds onto her cello, or only stand up for a few seconds. Pinkie's really the only exception for obvious reasons.



I'm not gonna tell you how to draw your art, since that's your area of expertise; all I can do is give my 2 bits as a fan of your art.
