Sorry, the other replies to this are completely correct that you should know your audience and flashy demos might also be a turn-off. This was a fantastic technical demo, I simply work in graphics so am biased towards that.

As a counter-point to the above commenter, I'm someone who's in an adjacent industry (HFT) and to me personally spending time on pretty pictures is a turn off. So I guess the take away is: know your audience.

I really really enjoyed your presentation, thanks for sharing.

I thought you did a really nice job with the slides. The diagrams made it easier to follow along.
