I am trying to model some human figures. The first picture is my latest model ( unskinned).

he looks somehow funny

I am doing a better head and face

It could get improved but like you mentioned, it's a test version.
Just mesh around with it until it looks realistic enough, the effort will result in a decent model

Cheers

Not bad but you can get good tutes on basic modelling online (doesnt matter what application just so as you see proportions and mesh line layouts) and keep in mind double segmenting joints for animating.
You also need to bear in mind bone placements and deformation (bending) and going from what you have showed, it wont take you long at all to build usable models.

I'll keep this prototype and use it for a small level demo , otherwise I would get stuck..it is a male model . Ages ago (think Kingping or shadowman) the model were not very complex but the whole game can create a great atmosphere.
I have to pratice in skinning and animating now.

that's better! but head proportions still can be improved

Make sure to use background images to use as a reference..... they help a LOT! Theres plenty of human profile pictures out there

Use a screenshot of a man, and put it in MED or whatever you model with
as abckground picture. You can use your Model, and adjust the proportions correctly.

I found very difficul modelling the head and the face staying in a low polycount ( the model is 1500 ).
