Just recently I created my first NFT collection on Opensea and I called it "Kyiv Fortress" because now my home city Kyiv is like a Fortress. Those photos I took before, as now to make pictures of fortifications in not good idea. The enemy's idea of siege failed, but russian orcs can return and there are many of them in the south and east of Ukraine.

I've been following NFT area for long time, but only now finally created collection. You can let me know your opinion, and in case there will be sales, I'll use the funds for supporting Ukraine.
