This is a rough sketch.
This time, from the beginning, I had decided to use Sechs as a motif.
My first image for the drawing was that he would stand straight. But in fact the pinup had much width in the size ratio, so it wouldn't work well as it was, because the both sides got big spaces and the subject became small.
Since it was unavoidable, I changed the plan to pose him to sit.

Since my condition was not so good, lines didn't run smoothly.
Usually I would draw the proper draft on Kent paper after that, then carry out inking precisely, though...
