I can only assume you used the old frame because of the step down in the middle of the door way?
to get a better seal between the top of the step and the front edge of the door what I would do is glue, with some polyurethane caulk, a strip of aluminum flashing to the concrete so you have a smooth strip for the seal to hit, with a good thick bead of caulk then close the door on it so it forms to the door, creating a smaller gap for the gasket to smoosh in to.
I would also do away with the metal weatherstripping and get some magnetic weather striping as it looks like you got the metal door, this weather striping is like a fridge door seal, it pulls the door in to it and seals tight!
