Pin10 rough design +update

So I was going through my doodles of Pinnochio and realised I still havent settled on one final image. So this is my attempt to summarise everythung. I know its not perfect, but with timeas it is I needed to get a design down. Any remarks would be lovely.
FYI the pink arent actual design.. colours.. I just wanted to seperate the possible line details from any sketchy lines I threw down...

update- Joey suggested a visible ball and socket, instead of my ambiguous gap, so here is a quick sketch of the proposed ball and socket. Im gonna drop this in to PS on top of e original drawing shortly, will make a new post, see how it looks
