Yeah, i see what you mean. 5.40 is total frustration. It feels like it's hanging on the verge of satisfaction but never quite reaching it. Rather unpleasant feeling I would say. But that's the whole point, right? :)
Whereas in my composition, I move to a chord V - G major in the key C - at 2.06, which causes the frustration to finally meet satisfaction (at least that was what I wanted it to do). And thanks for watching. :)
