Ooh I think I like the eyes the most, they're so pretty.
I think there is too much hard shading on the cup, it looks like she's holding it straight but the bottom is shaded like it's folding under itself. I would also recommend toning the texture on the hat down a bit because it's a little too prominent, making it feel flat.
I mean other than some shading advice I don't have much to say, it just feels very medium toned and could use some more darks and lights.
Yeah it can be tough knowing if you should enhance something or not, that's why in your earlier works I recommended making a new layer above all of your other layers and coloring it in black, then changing it to a "color" layer and you can see your image in black and white to see how the shading looks.
But I just realized I have no idea if you use photoshop.
