Most Led Zeppelin songs have a strong groove and melody, so that one should be fine. I do wonder, though, if you'll be bored just playing root notes on a lot of these songs. A lot of Pink Floyd doesn't have much bass fireworks going on. Just saying.
Anyway, if you are indeed going to be focusing on bass this time, look back at your video where you're playing the bass notes (the top half of the video). Notice that you're getting way too much clack off the frets and that you're not getting much sustain. Try to get a more sustained tone and get a little more out of held notes.
Yes of course, I scooped the mids because I tried to create a more "subtle sound" I guess, but I'll be using the 7 string you saw in the bottom of the video, flat eq and no reverb, I was thinking some overdrive but nothing too fancy
