Good job, it's nice to see Naruto's KCM in color. Btw, are you going to color the other 2 Bijuu, or just leave them white like that?
Their color is white,so there's nothing wrong with it.However,what does kinda bother me is Kurama's color.Since this is only a chakra shroud,it should be yellow like Naruto's normal Rikodou mode,but I guess I know where you are coming from.Since this form is closer to the original Kyuubi,making it orange does make sense.
It's probably just me,though.
Other than that,it's a solid coloring,even if I rather dislike the blurr effect you added to the Kyuubi's tails.
