I wouldn't say everybody is doing the same thing here, but that is the typical Sasuke coloring for you. Your generalization isn't to far off, but there are a few artists here doing more than just your typical 2 shadows, and a sharingan with light effects. Anyways, I agree that the way you colored the Hachibi makes it look more demonic, and that's definetly a good thing. I think it's cool that you tried something different, and out of the norm. Anyways, i've looked at your deviant gallery recently, and you have some good stuff here, and there. I thought your coloring of Tsunade's 163cm could of been done a little better, but I generally like what you do. Well, I hope you don't stop coloring things out of the Naruto manga. Sure most of its kind of simple, but if you're good enough you can always make it more intricate through coloring it, and adding more details.
