Your style is tight, refined, pleasing to look at. But a bit too bland. But that may not be really your fault. Since I find this to be a dime a dozen style. It doesn't feel like a unique piece.
Now this could be just because your particular style is just one that clashes with my perception in a way that makes me see this and not feel much elation.

Looking at this more. It could be related to how your shaded and textured this piece. Starting with her skin. The shadows are washed out by some of the pale moonlight. Not a problem smart rendering choice. But it seems the paleness of the moonlight is far too undersaturated. First off shadows are generally more saturated, while the only light that would make an object more saturated is a colored light. Such as a bluish moon. So I think the lighting would be a bit more vivid. And that could help with this piece.
Now looking at the texture on the leaf. It leaves(no pun intended) me with a lackluster taste in my mouth. Because it looks great. But it's the only clothing piece given that amount of attention. You may say that the rest would really have any noticable texture. but it is far more noticable that they do NOT have one. With how they were shaded as well they seem rushed. Overlapping fabrics can have a beautiful effect. But the way you have shaded is a bit non-sensical. Making the beautiful effect just seem... off.
My biggest point right now is that I hope you understand that you have skill. But your style seems to be missing a personal flare. Not all art needs that. If you are just wanting to pump out pleasing art for commission, comics, concept art, blah blah blah. Having a flare isn't needed. But if you are pushing yourself to be an artist. Then pursuing an artistic style and making it your own might be what you want to work towards.
