I actually think that your lighting is fine. My wife complained about the lighting around the mirror in our master bathroom for years. So I spent a lot of time working on the lighting in the new master bathroom in the house we are moving into. It lights us up very well when we are standing in front of the new mirrors. It lights us up so well that we can now see how old we actually look which is not actually that complimentary.
If you do decide to redo your lighting set up, don't just get brighter lights, find a book or Internet site that will tell you how to angle the lights so that they enhance your natural good looks without showing all the details of old age.
There are videos about EVERYTHING on YouTube so I will probably look up videos about proper lighting for recording YouTube videos.
