Hi Christoffer,
It's a nice touching story you have got here :) Simple and clean designs too.
Is that the low poly character that you are going to rig? I am working as a rigger and character TD, and if I would to rig a cartoony character like that, I would ask my modeler to add some loops in strategic places, where the character is to bend the most. One loop between knee and ankle, and hip and knee is too little - skinned geometry will collapse on bend, and specially on twist. The same goes for arms. It would also be good to add a couple of loops across the body and along sides of the body for the same reason. And at least one more loop across the neck…
Usually, I would ask my modeler to give me 5 loops across the joint. Say for a knee there would be a middle loop and 2 loops in the both directions from it, for getting a nice falloff in skinning.
I can see you have a nice little bend in knees, it would be nice to have the same for elbows - just to define where the elbow is, and to have an angle for IK handle to know in which direction to bend.
Just some thoughts 
Shape is very nicely captured.
Good luck!
I am going to join the video category too, as a team member :)
