Mate, those are seriously good. A lot of colouring is very solid (which is great) but I like how your colours are quite washed and somewhat transparent (I'm thinking particularly the Sasori one). The colours are vibrant without being...what's the word...so dense and solid looking. Kinda like Madhouse style (I love Madhouse's work).
P.S - you should do more! I'd like to see how you'd treat Itachi!
