Since there were drawing tutorial links posted.. I thought I might post some coloring tutorials as well. All links listed below are for PS coloring unless otherwise specified..
http://scroll.syste.ms/tutorial/tut1.html http://www.fireyskye.net http://www.ice-and-dark.net/furious/main2.html http://pendako.syste.ms/tutorials/tutorials.html http://www.portalgraphics.net/oc/index.asp?reqLang=en (under openCanvas space.. then CG lecture, for oC only)
http://www.pastime.ne.jp/howto/cgkouza_1_2.htm (in jap but has pictures)
http://www.lucentcanvas.com/extras/t...tutorial.shtml (varied - traditional + painter)
These are supposedly the good CG tutorials I could find.. hope they help (if at all). If you know any more though, just post them here.
