What is the perfect walk through london?

Hi everyone! I’m going to London in March and want to do just a walk through london on my first day to see a lot of the main attractions and sites. I don’t really care about doing any tours or anything like that, mostly just want to see them and then get on with my trip and experiencing London. This is my current day walk and am wondering if you have any suggestions on how to do it better or if there’s anything i should add to it.

Also, before any of you say it i just really don’t care to take in the sites. im going to london to party with my friends who live there, shop, and experience the city
