Not a master, so no bowing please
anywho, if you are looking for strikes for a character whose basics are striiking and whose advanced waza are throwing and locking, I'd consider the following:
Low kicks to legs
knife edge strikes with the hands
palm strikes with the hands
nuckle strikes to soft parts
maybe some knee strikes.
Then set up your character to do throws and such from there. Sounds like an interesting project!
