Thanks for the feedback, really appreciated!
I actually had kind of noticed the videos ending too quickly when I was editing them - will let them run longer. All part of the learning process!
With regard to updates, I have more that I am going to post over the next couple of weeks. But more content will follow when budgets allow.
Take your point about the prices. I guess it comes down to economies of scale. This is a pretty niche fetish, there aren't thousands of us. And even fewer who are willing to pay. So I never expect to sell a huge amount of these. If I thought I could cover it by charging less, I would. I have a shorter video that I'm posting next (the first one I ever did). I'll price that one lower and see how it goes.
