Tweening
For me, I tried the wet-blending thing, and I got ok with it, but it\'s really, really time consuming, and takes a lot of patience. I pretty much decided I could get similar effects, with much less headaches, just doing a bunch of layers.
Recently, though, I\'ve started playing with a technique that I like to call \"tweening.\" Partly because it\'s such a fun word, and partly because it concentrates on doing blocks of the basic colors, shadows, and highlights, and then working the areas in between them to make them smooth (a lot of computer animators call this process \"tweening\").
Check out
this article on PlanetFigure for a really good discussion on it.
Apparently, Theirry (a former Rackham painter, goes by Arkaal here on CMON) uses this technique as well. I\'m definitely nowhere near his level yet, but my initial work with this technique has been really encouraging, and it\'s definitely something I\'m gonna spend more time on.
