Oh so close,,,,but between B and the right end, the shear diagram is wrong,,,you have a distributed load there so the shear line is not horizontal. Your moment diagram them gets messed up between B and the end because of that shear error. And by convention, moment diagram is not mirrored like last time , this is a good thing
