Hey there, in this thread you can find alot of teachers in the tb community: http://forum.toribash.com/showthread.php?t=559233
There are also a couple of art teachers in there, might shoot them a pm and you can get help.
Thanks but the problem is I already know the basics.
The three teachers listed are people I have met in the past, and I know for a fact my abilities have far surpassed theirs, even down to mapping. (sorry weeooo). I need someone who is exceptional.
Have a quick search for pheatures complete texturing tut. I'd link it but I'm on an iPad, being lazy. He touches on mapping very well and has images with colour mapping to mark areas you would map, and and a good way to consider points of light in tb
Fuck it I'll grab it in a sec, for now this is also a good tut. http://forum.toribash.com/showthread.php?t=91748. Written by Monobi, who I personally consider the greatest artist to grace us, simply because of his creative nature, he was never really recycling his ideas
Sorry that didn't help. You could tey hanging around the members of [CT]. At one point pretty much 80% of the active art community joined it.
Try asking Calamity, if he's not busy he may be able to apprentice you of sorts. You could also try Jebus, but he is more inactive. Just two suggestions of good artists
