I agree with you insulating the rim joist with foam but what about the walls ? You paid to insulate the block cores which probably cost just as much as spraying the entire wall with foam. Also insulating the cores does not prevent the transfer of heat or cold thru the block wall. Also you have plastic down as a vapor barrier but used open cell foam to seal it. Open cell foam in NOT a vapror barrier at any thickness !!! Good job on using foam but I think you should read up on it a little bit more
