It's very good but here's some advice and things to work on
-keep it clean, the main thing I noticed was that it wasn't so clean, the key to making it look great is keeping it clean and neat.
-work on your lines, try and keep them as smooth as possible, I know it's very hard but draw them carefully and keep them smooth.
-work on your shading, I realised your shading wasn't so flat it was more lines, if you are not already you should use soft dark Pencils like 4B-6B for the hair, also try make the shadows in the hair stand out.
-lastly try and make the drawing fit the whole page and if your inspiration image doesn't go further use your imagination and extend the drawing.
Overall 5/10 it wasn't perfect(neither are anybodys) but there is still loads of room for improvement^.^
