Hi there, good quality video and you explain everything very clearly. I can tell your series of vids is going to be helpful for a lot of people out there starting out.
My main critique though (a constructive one), is that you just took liberty of boosting a high shelf without actually listening to it and then moved on to the next frequency range. Same with how you cut out the lows without really listening to it. Perhaps you do this because your thinking it just "looks" right on the graph and because of the mentality of "well I cut this frequency out, so I should make up for it here". However, I understand your logic and that everyone might use different eq techniques.
All in all though, you did a great job at demonstrating how to sweep around with a narrow q to find the offending frequencies. And that was the real purpose of the video, so yeah!
On a side note, I remember watching a video showing this, but the guy was sweeping around with a super wide q, and obviously he very easily found a large range of ugly somewhere in the mids. Once he found the wide ugly range, he didn't narrow it to really focus on only removing a specific frequency, but rather kept it all wide and scooped a whole bunch out. Which in theory will just leave your track empty and hollow sounding, since he's removing some frequencies that don't need to be removed!
