I'think the nose's shade should be mirrored and you should get rid of that black japan-shaped dingy in the down right corner. Also I think that the eyebrow (is it?) goes too low in the midle. I'm talking about the first face.

Little update Thx Kaczor (you can speak polish if you answering on my post ;P).

On the second one, it looks like he's puffing out his cheeks. 
And they both look really pissed off.

But other than that, great job. Your good with lighting, i can tell.
