This is a really cool submission, I love how energetic it is! As a beginner myself, I'm also impressed by the sort of audio depth(?) of the instruments, how none of them seem to be overlapping. What I mean is, you can hear the sort of distance between the sounds/instruments in the same way you would when listening to a live orchestra performance. I don't know how you achieved that but you did it really well!
The piano at the end is my favorite part, it sounds so graceful. I especially love the part just after 1:40, the harmony between the lower notes and the higher melody sounds amazing :)
