What I like the most are the abs and the trousers. Well done, I really mean it. Obviously the wings could have a lot more detail but they're fine and more efficient as they are. The hair looks good but the pale lines are too noticeable and the hairstyle could be better (also, the two curls seem out of place).



The major issues are the face and the physique in general.

Face: Perspective is flawed, muzzle looks very odd and eyes look decent but could be definitely better. Additionally ears look a bit weird, especially the way her left one is attached, and neck is a tad too long.

Physique: Proportions are bad, if you exaggerate abs to such an extent you should draw her athletic in general or the physique looks completely off. Her arms are attached far too low and are way too thin and fragile. To improve proportions, you could add a smidge of obliques, traps, delts, lats, even a bit of chest and slightly thicker upper legs with more pronounced quads, hams and glutes.



Now to more subjective or trivial matters. I personally don't like the ear piercing as it is, breasts are a bit too large (bra is good), no nipples and fingernails, a more energetic facial expression would suit the lively active RD better, as well as more sporty shoes (the current ones look nice though).



I think this is the better version as it simply has more detail+better shadowing overall and because of trousers and abs but what I prefer about the original are: facial expression, physique, proportions, hair, hairstyle, shoe type, ear piercing location, breasts, background, gloves. Keep in mind, I only think that those are better to a various degree, not that they are perfect.





Overall I'd rate your art clearly above average for fandom standards but with much room for further improvement. Some of it is simply even more detail, there it's a question of efficiency, of how much work you are willing to invest versus how much output you want. The other is stylistic, perspective and proportions. I don't know, maybe you like the current style. You are the artist, you can draw whatever and however you want.
