To improve score: upgrade your bread, get some proper mature cheddar in there, triple the ham, or get the good thick stuff, spread some mustard or chutney in there and finish off with some pickles or go out there and put some olives or tapenade in there. Really lifts the flavour profile

Poor bread, floppy and mass produced. Sparse cheese. Thin ham. No evidence of condiments besides butter. I’m sure it’s fine, but can’t give it more than 5/10
