Would love feedback

Hi! I would love to get some feedback, tips, resources, etc. Mixing is for sure a weak area for me, but I’m not well rounded anywhere so anything helps. This is the project I was working on for the ASFX contest (I set it aside when the April challenges started here).

All sounds are original- about half are synthesized and the others were recorded on my phone. (Originally I had 1 synthesized project and one project built on recordings, but I wasn’t able to achieve everything I wanted with just one or the other.) I have not done any projects with visual media prior to attempting this, so really anything is helpful! Thank you!
