I really do like the way you made the colouring. It looks very clean and well done.
I also like the way you drew her hair.
It looks smooth and soft at the same time. What also looks good is this 'blury filter' it let look the pictour original and 'unique'(?).
The highlight, the shading and the line art are very well.
The only thing that 'bothers' me are the eyes. Or the lashes...? I think that they are a bit too long. But I also think, that it's something like my own opinion.
All in all the fanart is really well drawn.
