I wouldn't be unhappy with that paint job, looks great to me.

Yeah, man, that doesn't look too shabby. If you want to add some more depth to the colours, you can always give them a wash. Preferably thin your washes a bit with water as they tend to be a bit too dark. It's best to work in layers, rather than to try and achiev an effect in go and easily smothering your model.
