I'm already a step ahead of you, I have a version of this model that has broken cuffs on the wrists.
Other things: I model the head from a box. I used to use bridge to attach it to the body, now I just target weld it, it results in a cleaner mesh. For the hands, I started with a 3 sided box and just moved it into the general shape with a few extrusions, no fingers, just a thumb. I've just reused the same hand for all my models, target welded.
