Hi Jon, well done in achieving this, especially in what appears to be a tight turnaround it getting set up.
Amazed at 1/40, but the flash really worked well, nice techs & DoF. I just wondered about a little less below and a fraction more above on a 16 x 10 format? On the laptop it looks a bit flat, but that isn't a good yard stick.
It's nice when you find a cooperative subject like this! Excellent sharpness and detail within your DOF plus pleasing colors and comp. Very nicely done!
