Ahh yea I saw that one. Looks really good, but the pen tooling seems too straight, give it a more smooth / curved look. Other than that pretty damn good.
Pretty awesome imo. I like the bundle of colours and very smooth curving there. But the other lines, along the body to the left looked a bit jagged like Vir4l said. Cool concept
I kind of enjoy the jagged straight lines on the left side. It is kind of an anti-flow, which then would contradict your title choice. Nonetheless, I like it.
