Hi, we have recently updated our showreel video and called it "Shoot 4 Business Success".

Any feedback on it would be appreciated.

It definitely looks professional.
This I would change:
First clip with green screen (around 00:37) either do some more work to it to remove some of the green spill or just take it out of the reel. You should only have the very best stuff.

Not loving the color scheme on the shot at 00:19, dark green background with reflections just look odd imo.

The quality of the real video stuff is great!
