hmmm im guessing you're drawing the fable guy in your sig? the only problem i see is that you're thinking about "where do i put the detail" rather than, "how would it look", i used to, and still do this myself. Basically the way i go about thinking about it is think where the light is coming from, and the ammount of contrast i want to give, to do that you have to think about where the light is comming from and the planes in the picture (planes are like faces on a model) the more a plane is directed at a lightsource the lighter it'd be. The point being is, if the light was comming from the left in your picture, you're guy wouldnt have a line at the left side of his nose, it'd probably be on the right. Understand what im saying? >_< its really hard to get across what i mean.
