A nice comparison in comps with #4 and #6 where as the entire insect is in frame versus an excellent angle with a partial insect. Nice that you carefully caught the whole wing tip and tail in #4 and that your are lead up the body to the flower. As for #6, it is truely one of those excellent comps and shots. The light is incredible, I don't know if you needed to stack here since most seems on the same plane of focus but it you did I do like the way it fades back to the OOF area seemingly. There is an awful lot of good experience and careful work that I believe went in to making this shot superb, you did very well IMO!
