Go back to your old style. This is what I would expect someones first head to look like.
First: The hair is just terrible, its one solid chunk, of two separate colors. It has nothing there to make me think its hair. For all I know without you telling me, he could be a spaceman with a large chunk missing from the front of his helmet. If you would like some help on how to make it look like actual hair, check this link out:

It applies to making hair on toris as well, because the concept is the same, despite the tutorial being for a different purpose.
Or, if you want to stick to cartoon style(don't, its what everyone does nowadays), check out some of the better cartoonish heads in the head expo such as these:
I in no way am telling you to copy their styles, but, study them, see what they did and what they didn't do. Then expand upon that yourself, see what you can add to it, and make your own style.
Second mistake I see is the mouth: The blur you applied to it makes it look bad. If it isn't a blur, then I don't know what it is, its very fuzzy.
Lastly: The eyes are too big.
