The Kyoujin's Work

[Hoeloe]

The shading on the back leg of those tengu looks really odd, and there's a fair bit of banding.

The first guy's face is also pretty hard to read, maybe tidy that up a bit?

Otherwise, from first glance, those appear to be pretty good.

The bottom one looks quite odd, though. The black makes it look messy, and a lot of the colours blend into each other. The shading on the hair is also pretty weird.
