Oh boi. You have just made one of the most meme-iest jazz songs I ever felt and heard. It all starts with feelings of happiness, when suddenly you changed the tone near the end of the song, making it feel like I'm on the run. But there were a few problems though, the solo piano at the very beginning felt a bit too crowded, maybe add some reeverb to free up some space for it, since it is the only thing playing at the beginning. Maybe add some for the saxaphone?
There was also those drums, I know they were probably not your main focus through the whole song, but maybe you could try to make it stand out a bit in your song? It's just a suggestion tho.
Overall, great song you got here. I hope you enjoy making them meme-ish jazz songs, because I'd like to see more from you!
