Not bad. But your paint seems very thick-- try applying thinner layers. You may need to apply two coats instead of one to get the color you want, but the outcome will be -much- better. Be sure your brush is wet, and you're not taking paint straight from the pot and applying it to the model. Take some paint out, put it on a palette, keep your brush wet, and apply thin layers. While you can sometimes get away with thicker coats on models like Space Marines and Tau, Eldar are very thin, fine models, and thick paint obscures detail much more noticably than on models which are mostly flat surfaces.
