Inking and drybrushing are great ways to do metallics quickly and easily, especially if you\'re just starting out. Having them totally solid like that doesn\'t look very good, especially if they are pretty much the only accent color on the model.
Try these out a bit on the next one, and remember you can go back and touch up the black armor around the metal afterwards. Mixing a little black ink in with regular Chaos Black is a good way to do touchups around trim, the paint tends to stay in the cracks easier than regular thinned Chaos Black.
Don\'t be too discouraged if your models progress slowly, especially if you don\'t have anyone around locally to paint with. You\'ll occasionally have a few big jumps in quality if you follow the usual trend of gamers.
