Yes, it would be nice to have the crits for mental (traumas, that need counseling like in other YZE), two tables flavored for physical/mental.
I would like to suggest change for crits "Crushed/Broken bone" instead of Crushed arm, and "Multiple crushed/broken bones" rather than Crushed leg, this would fit more neatly with the crit going up a level if lower one is rolled. Oh you had a broken bone, now there are more. Also a suggestion for that lvl8 multiple crushed/broken to be -3 modifier. Perhaps lvl9 as well. Then lvl10/11 are -4 (I mean, you are a pulp/skewered). Just some thoughts.
You could have separate roll table for which bone(s) [granted the GM could do this, but having table/specifics always helps offload the GM needing to make it up on the fly]
