If you could post the reference photo you use to draw this that would be great

.
There are some criticisms I have and I assume you want to hear them.
The ear looks odd, like it is being pinched inward (unless this is what her ear actually looks like).
There hair seems clumpy and greasy from all the shine. It looks weird because it gives the appearance there are light sources everywhere, rather than just one spot.
The bottom right of the nose looks off (too large on bottom right side), but you already said that, and I think noses always look weird.
Looking at photos of her, her top lip looks a bit too large and the distance from her mouth to the nose is just a little bit too wide. Her head also seems a bit too wide and not as long as it is in real life.
I would recommend trying to draw some more bone structure such as in her cheeks, creases like above her lip, and more pronounced details around the eyes, especially below. If someone is smiling I would expect some more creases in the face and that her cheekbones be more pronounced. The picture just looks too smooth and undefined in my opinion.
I hope those suggestions help you! Great picture and keep up the nice work!
