Hello Sandor,
the first two photos looking nice. The armour is very nice painted.The other two as well. But be careful with the faces, try to reduce the black to a minimum, as well as the extrem lights.
When I was a young boy and painted my first flats, years ago, an old painter told me that with a bad painted face you can destroy the whole figure. And I must say he was right. Sometimes I paint a face three or four times to give it the expression I had in my mind.
