Ok decent
This was a nice idea to take your last inktober work and add something to it. It is like you took the shell of the art and placed it as a focal point with a nice artistic style. I think the way you kept it more as a sketch was an interesting choice and the fact that each version of him isn't exactly the same was also a nice touch. I think overall this is a good job but I would add up a border to this one as this one could use more lines to go with the nice textured lines within Luffy.
~~THINGS TO IMPROVE ON~~
Add a border to match those nice lines within each Luffy.
