That's a nice little resource there.
I thought this was gonna be boobs vs butts or something! LOL Looks to be more about art styles, though. It's somewhat difficult to explain one's preferences regarding artwork much in the same way it's difficult to explain a particular fetish or preference for a certain color or texture. It really all depends on different things and I don't think there ever is any one style that covers everything. For instance, I love Shag's work (Josh Agle) and own several pieces by him that decorate my home. They lend to a certain ambiance and just make me feel good to look at them. I own several pieced by Ragnar, purchased for the same reason. Now the art of both of those individuals isn't erotic at all to me, but I love their artwork, even though it's VERY 'cartoony' in nature.
The kind of artwork that gives me raging 5-alarm boners on visual contact is the style used by Adam Hughes, Alex Ross, Frank Cho, etc. Turk has done some pics in the style of Cho (because Turk has many different styles unlike those guys mentioned) and those are the Holy Grail for me. I like his realistic style with unrealistic proportions (if that makes any sense). Here, I'll try and explain....take a sexy regular girl, drawn in a standard Marvel/DC comic style, and load her up with massive boobs, a big round booooo-tay, and if she's a futa, a huge thick 2 foot dick and balls.
Boom! Instant happy-house dance begins in my pants whenever I run across that kind of thing anywhere.

They Disney style is awesome, but I'm glad when I see some of the "superhero-y" styles too.
