No problem. You make good stuff, so it’d be a shame if people couldn’t use it because of quirks in their country’s laws.
Having stuff under a proper license also means that I can add it to the list I’m building to help people find assets I wish I had when I was a kid. (I was learning to program but had no pixel-art skills. I ended up giving up on games and doing non-game programming instead.)
That said, I notice that you made the same change to some of your other assets, but the description says “Licence is under CCBYSA”. You’ll want to change either their descriptions or their “More Information” blocks so they agree.
