Overall, a fun little submission!
One critique - some of the synth sounds you used sound a little rough around the edges, especially the higher synth guitar in "Save the Summer." Adding some kind of modulation or oscillation to your sounds can help to alleviate the harshness and give it a more rounded sound.
Don't forget to put chapters in your youtube videos! (just type in the description like below)

Regardless, nice work and thanks for sharing!
