Experimenting with faces

[Ralphonso]

Figure painting eludes me. Sometimes I can kind of get it, most times I don't. The problem is that I do not recognize what I'm doing differently when things go right, so that I can keep the good results and discard with the bad.


This fellow is from Tamiya's Sdkfz 232. I painted him with Vallejo. He looks okay from some angles, and very horrible from others.

Suggestions for improvement?
