Couple of thoughts (Feel free to ignore): 1 - "Novari is Spotify for generative art" could work harder for you probably. Ref https://www.demandcurve.com/playbooks/above-the-fold#i3q8kwg...
2 - I wonder if use cases might be better to highlight on the home page, e.g. mock ups of the art being displayed in your home on digital frames or screensavers, whilst there's a part going on projected etc.
3 - The art is the wow factor right? So once in the app once you've signed up maybe it's a good idea to present users a big play button that shows them art immediately, reducing time to figure out what's on there etc.
4 - If you are viewing art on the full screen it might be good to be able to scroll through it without pressing esc and the next piece?
