Lovely concept, but if I might offer a suggestion:
give it a little twist everybody knows th epoor bastard keeps falling of the wall and cracks his hat like this:
Maybe replace the hat with a builders cap and place some matrasses around the wall some knee and elbow pads, some safety goggles, maybe even add a securing system that builders ( ought to) use when working on great altitudes.
Than maybe you can sell it( the animation) to some buildersunion and make some money with what you like
win-win I 'd say
Good start nice topology from what i can see as well
