His name is Yuriy Gusev! He's in his early 50s, and has a sad story: his daughter passed away 8 years ago, and she was only 18 years old. It's amazing that someone can make such intricate and beautiful pixel artworks like these, I know how hard it is! I tried once and could barely make a character sprite...

It's interesting that you first mentioned how you're unsure about sharing this because you're earning money from it. On "art Twitter" there's been a huge issue circulating around one instagrammer who thinks of themself as a curator, posting other people's art - with credit most of the time. The problem is that in every comment they would have their PayPal donation link and say something like, "link to donate if you want to support me" - kind of insinuating that they did the art. Anyway, Twitter blew up and people harassed this person until they took the donation link down. Their account is still active and they're still sharing art, just without a personal donate link.

I'm not sure that what you're doing is bad, because Steemit is more like a blog and people aren't directly giving you money for the art that you post. They're simply upvoting because they like what the post is about, and it happens to have money attached. So I think you can share in this way artists that you admire, as long as it's not the majority of your posts.
