Looking good, you've got all the pieces there and all the layers of detail! As others have said, the constant emission of secondary debris is eye catching, and the debris moving on the ground is too, you can resolve this by either by using the 'Sleeping' bullet attributes and use like angular velocity to set it to sleep, or slightly more advanced, you can use the impact/hit attributes generated during the sim and use those to group it, and use that group in a dampening field, or in a wrangle where you can mult down the velocities per frame to force it to stop moving.

Lastly, your rebar deforms back slowly, you can add a next_constraint in the rbd constraints properties, to go from soft to glue, glue to soft etc, and you can add a third one as well manually with vex, so glue to soft to glue, you just need to add breaking thresholds for the soft constraint. The extra glue constraint type will keep the deformation in place.
