You've got two unused overall segments and four unused North America segments. I'd change BOS-LHR to BOS-DFW/ORD-LAX-LHR. LAX-LHR is a much nicer flight if you'll be in J or F.
You have two visits to Asia, which is fine since one is for transt between Europe/Middle East and South West Pacific, but I'm not 100% sure if you can have two stopovers in that transit.
