ricci has a nice youtube on vamping. as i understand vamping- it is a common riff/hook that is short. could be 1 or 2 bars. from there you go off on a improv. but you always come back to the same riff/hook. the improv could be 2 bars or maybe 6, but you keep coming back home.
what i heard doesnt resemble what i always considered vamping.
but there was lots of good stuff in your playing. what was that opener. it sounded familiar but i just cant place it.
