On scope, that was a big lesson for me where I actually had some success in working with a limited timeframe, but only because I have been doing these jams for a while. I'm really glad you brought up the time constraint into this - because that is actually a place where feedback can still be helpful.
What you did in the time is still pretty good. Definitely looking forward too hearing your work in future jams!
Great job, and good on you for submitting despite the time pressure.
