A boy

I keep trying to draw humans. The idea of this one is a boy from streets. With clothes looking like being used before by people with other sizes. And still the colours of the clothes go togethter more or less good.

My main problem with the faces is dirt that comes out of the coloures that I shouldn't mix. The colours are good and natural in legs and hand, but I am overtrying to draw face. But this time I made the cheeks and shadow under lip.

And I need to pay attention to hair, this time it doesn't matter according to the plot, but it is absolutely different from what I mean for it to be.
