Deej,

You are one of my favorite vocalists here. Never a disappointing experience. Actually, I liked this tune a lot. Probably would make first 3 top songs by you on my list. Excellent lyrics, vocal performance and arrangement. The "abrupt start" you mentioned did not bother me personally at all. However if you want an opinion, there might be an easy cheat/addition to make intro a bit more smooth. After the last "knock" consider a sliding note of a bass or other instrument that would lead into the tune. In any case amazing effort and thank you for sharing.

Misha.
