Trying won't kill you, try to draw eyes, re-draw them, draw them once again until you think they look good enough. Practise makes perfect, as for what you have right now, it looks decent, I would suggest to try the same concept a few times, change the hair style, change the mouth (for example, open mouth, smile, mad). Try experimenting with differnt expressions and you should be good to go, I like how you didn't use too many hard lines on the hair, good job.
