It's actually very pretty! You did a pretty good job on and and facial details.
My only suggestion would be to work on hands. I know hands are very, VERY, hard, -I draw realism and semi-realisim, and you don't want to know how many drawings have been ruined because I couldn't draw the hands.- but with practice, you'll be able to get them. I usually don't draw or look at manga anymore, but this is very cute!
My rate would be 8.3/10.
