Ok, my first drawings most of the lines a little too thick and the ones in the previous post perhaps weren't thick enough. I decided to imitate one drawing that has already been inked so I could get a better idea and that's the result. The original one has some better decissions like making the arms more separate to the body (wider arms) and the cheek on our right looked better, among other things, but I'd try to apply this thicker lines outside with thinner things inside in my next attempts.
Here is the original. Incidentally I inked the pencil drawing, of course. I just took a look to the inked one while doing it. I made the smile line thicker cause John said it was thicker in the original.
