Your presentation is good, even if the tone misses the mark.
Some constructive criticism: I'd work on mic placement and amp settings a bit more. Stay off modern mode if that's what you're using (sounds like it). You'd get closer with something like a Beyerdynamic M160 ribbon mic than an SM57. C90 speaker isn't ideal either. It'll compound the scooped tone in modern mode. 50 watt Rectifiers are more strident than their bigger brothers, so you'll be fighting all those factors combined.
The tone in your video is more congested and ratty than Linkin Park's first two albums. Their isolated guitar tracks are warmer than you'd expect. At least you acknowledged that they didn't use Rectifiers alone--the reality is they weren't used at all. I'm a big fan of NRG Studios and have done some deep dives into their work with regards to guitar tones.
