Well, I like them a lot. It’s fine for people to ask why, but sometimes a project is just a project. Or maybe you wanted them for yourself and decided to be kind and open them up for everyone. In the good days of the Internet, the response would be: “that’s so cool! Great job!” I think that’s warranted here.

If I had to be nit-picky, my feedback would be: the lock and unlock icons are a bit too samey at small sizes on my non-high-res screen. Perhaps make unlock a bit more obvious? Shorten the open loop area a little more?

I think the heart might need a bit more dip at the top, too. Up close it’s a heart, but from further away the top part gets a little lost.

Finally, the laptop icon feels slightly off to me. I think maybe if the bottom “keyboard” part extended a little past the screen on the left and right it would feel better? Not sure.

I’m no expert on licensing, so double check that’s right. And I agree that you could probably crush them down more with an optimizer, but so can I. That’s easy enough. Overall: I like’em a lot! Great work. :)
