topology

Hello. I have a problem with appearing normals (shadows on the surface). I am sure that i am doing something wrong in the topology. Please one of the good modellers can tell me what i doing wrong and how solve that to make smooth normals? I've also attach two screenshots that showing the problem.

Turns out there was this very essential thing called topology I had no clue about and yet, found myself in need to learn and use to rework my mesh nearly from scrap. With the right references and some improvisation, it's coming along nicely I'd say. The armor will be done after rigging/sculpting.
