I\'m here at last!
LOL... See what happens when I get busy? I almost miss a
tweening post. lol
You know, it\'s kind of scary that I\'m so associated with that...
Anwyay, looks like most of it has been covered, so I\'ll just throw in confirmation that yes, Arkaal uses this technique for his NMM (and, from what I understand, pretty much everything else). Well, confirm as in \"I heard from someone that they talked to him and he said he does this\" mostly, but also that I\'ve extrapolated that he does this by reading a few of his articles over at the Confrontation painting forum a while back.
I do find that tweening is easier than feathering for me as well. They\'re very similar, but the main difference is that you can block in *all* of your layers and let them dry, and then go back and tween. When you feather layers, you\'re typically dealing with thicker paint than you are when you get to the tweens, and it can be a bit trickier to feather out nicely.
