heh, seems i left an impression on the public back then.
i like the heads. well made. hair is well shaded, specifically on the third head, the shading on haijin and dogu is a little random in comparison
they lack variety though, think you should have gone for totally different looks for each one. u seem to sorta be using a standard when making them. could vary the hair and eye styles/proportions alot more i think. also, ur allowed to use awesome hair colours hey :P
redoing characters from actual series usually gets good reviews from the community. hint hint :P
