Personally, I would apply your flesh colors first then decide if you need it to warm it up or not. If you do, apply as a wash.
Glad its turning out for you!!
You know, I love my genesis thinner too, but it seems like I go through a lot more thinner and paint that way then when I use spirits. Or is it just me?
I love yellow ochre, but not for every kit and of course very thin.
