On Drake's prompting (and in response to David's questions) I've finally decided to put a tute together. Ironic that it's taken this long since I was the one who instituted the Tutorial thread with Kuma's help so long ago now.
At any rate, it's a simple one, that explains some of the process I use to colour a vignetted character ala WOTC. But the process does extend somewhat into full page painting as well. With this tute I'm trying to extol the virtues of using layers and the advantages that they offer. I hear many digital artists say just let yourself go and utilize all the mistakes that arise using a single layer to help give a traditional experience. I say rubbish to that. When you're in this for business I say use every tool at your disposal and try to make the job go as easily as it can. If using multiple layers can provide that go for it.
This was a character I did for Sacrosanct Games by the way. Which was intially done greyscale.
I've now ported links to all those tutorials over to a new site - the Art Tutorials Wik. The material there has been vastly expanded and now has links to more than a thousand tutorials.
Furthermore, it has some original tutorials as well - such as my Digital Cartography Tutorials. If someone here is looking for a place to put his tutorials, this Wiki allows you to upload and use your own images on the pages as well (though you'll have to register at Wikidot.Com to be able to upload files).
