That's the first time I felt like I', reading a ninja story. must be the pose.
Great colors Hiruko, I like your chose of contrasting colors and the cleanliness of shading.
My only comment would be the shadow under him, it looks off and unrefined (very contrasting to the beautiful shading of Omoi above)
Nice Hiruko, I like it. It's to bad you didn't color the whole double spread though. Then again, that double spread would be a lot of work to color, but I think it would look really good in your coloring style.
