Keep drawing, I guess you could say when you're a drawer criticism if something that helps you draw better, keep practising and take everyone's thoughts into account, I've been drawing for a year now, I'm still not that good keep trying, if you like to draw on the computer try investing in a tablet, I did that and it helped out with my paper drawing as well.
The eyes over the hair is done in a lot of anime artworks I've seen on DA recently so it's fine. But yea, in proportion to the neck, the eyes are rather big. Just do some more sketching to get the right head proportion. Don't forget that the hair line is pretty high too, so the top right hair part could be raised more. :0 Otherwise, for just beginning, it looks fine. I'd recommend you try to sketch different poses and angles every now and then, it'll really help you to understand anatomy, the most important part of anime, lol
