I love this piece. It's got a great and multi-faceted introduction part of which you bring back near the end with the quick woodwind gestures in the background. It's very bright and happy and I know you were worried about sounding like a copy of John Williams (he does have a particular way of using 4ths and 5ths that can be cliche) but I don't hear that - it sounds very unique and individual. Great job!
I appreciate that Left. I agree that I may have just unintentionally borrowed the chord progression, but I'm glad you think it's nice. I've picked up a few tricks in my time making music, and am proud of what I'm doing now. Thank you for your feedback. I look forward to learning and growing with you all.
