Icons look great :) You have a designer's eye. I think for cartoony icons they're a little bit too realistic - not that that's bad, you just might want to change up your style a bit (less colours per icon, thicker lines, more saturation) or rebrand it. Really up to you though, they're great as they are.
You need to beef up your product page though, it feels amateurish. If it were me, I'd:
- Continue adding stuff to the pack
- Gradually iterate on the product page
- Build an audience off-site
Good luck!
