It's a good start joopson. The main area that needs work is the bit where the nose joins the upper lip. Also the ears could do with sticking out a bit more.

Not sure if this is supposed to be a child, but at the moment the eyes are looking way too big for an adult. I would also try and soften the side of the temples and spend some time working on the jaw line in the side view. Lastly I think that you need to seperate the lips, not so that the mouth is open, just so the upper and lower lips are better defined.

Hope this helped.
