Kuro, I want you to use more reference on these people, try to mimick the style as well as possible, as a DBZ freak (I'm watching all of the episodes again in HD, analyzing and all that jazz because I'm a hermit and DBZ was my childhood) I want to this stick out a bit more from the other generic DBZ rpgs. This goes for you as well, Batlorder, remember that Z is cel-shaded guys, so try to cut down on colors, also remember that black outlines are in Z.
Another thing to note, from what I've noticed with DBZ MMOs, there tends to not be enough variety with hair, so try to think outside the box a bit, use more than just Goku's, Vegeta's and Trunks' hair. Same goes for the classes, remember theres more than just Majin(which no, possessed humans aren't Majin, I'm talking Majin Buu), Saiyan, Namek and Human.http://www.maiken2051.com/images/cropped/Goku%20Yardrat.jpghttp://digilander.libero.it/SKIZZATI/images/dragonball/vegeta%20vs.%20goku.JPGhttp://img444.imageshack.us/img444/5455/vegeta21cc8.jpg
Remember when you're making the hair, it isn't really shaded when its black, when its blonde there tends to be three shades (white, yellow, dark yellow), when its red it tends to be two shades (red, dark red), when its white it tends to be two shades (white, grayish sky blue).
Remember when in the Super Saiya-jin state (i.e. Super Saiyan, SS, SSJ, whatever), their moods are changed, remember on Namek Goku had to try and fight his inner demons with this new transformation, to say his good self, not just fight Frieza. Super Saiyans tend to be very primal, angry, not as much as an oozaru but thats kind of the point, its a controlled oozaru state.
Vegeta can go both ways, with either slight "brown" hair or just straight-out black, I would argue black is closer to the original since he only had his "brown" hair in the Budokai games, even in the new Dragonball Z episode, Vegeta has his slick black hair.
