Hello!
First of all - it is a masterpiece for an amateur like me<img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="391" title=" (Smile)"/> You are awesome and I want to become as skilled someday. But this is what almost anyone here could tell you ahah.

I am confident that you know about unsymmetrical nostrils here.
Also there is a line on palm that wasn's post processed. And maybe it would be better to let viewers to see more precise borders of hands and face.

Looks like my opinion is a bit cruel so far..
I must say now that this art is done incredibly well. I really adore the hair and nails here. Contrasts are also remarkable.

Wish you any luck! Keep making great art!
