I also started to paint one more gobber today, but I think that I honestly failed with the skin. The drybrushing just made it look weird instead of a lean green machine. Gotta figure that one out. I've got no less than one lots (technical Mekboy term mind you) of Orks to paint even for my 750p list, and a lot of them have green skin to be painted. Or I could turn it around, after painting that many Orks I better improve my technique *somehow* :) And one nifty thing with Orks is, they shouldn't look uniform, so if I try out different colors and techniques, that is just Orky anyways.
In Space Marine land I've painted a termy today. The GW foundation colors thus far has been a hit. I recommend! Go buy!
