I am trying to increase my art skills (shading/light sources/anatomy etc) I have found a few sites but they are really basic stuff and I was wondering if anyone could recommend a fgood starting book or site to start me off. I can copy a picture perfectly by hand and my lettering is ok its mainly the shadows and things i struggle with. I've tried the squinting method but I can't really get it (plus my contact lenses try to escape) I dont want to go through my tattoing life just copying flash I have amazing ideas I cant translate to paper. Luckily my friend is an amazing artist and is willing to draw anything on request, line work and colour version but I feel I am cheating somewhat and I'd like to be able to look at a finished (or maybe not) tattoo and just know where to add a bit here and there to give it that extra bit of depth if that makes sense instead of constantly referring to my picture. Thanks in advance for any idead / advice. I do have paint shop pro I'm using atm to to all the work for me!
