I was delighted to see this name pop up in my HN feed of all places.

I've the joy of being married to a fantasy illustrator, and through her I've been able to attend a number of fantasy art conventions and shows. As I've seen a number of comments as well as the article asking about such, I can say Boris is doing quite well! He's a regular fixture at Illuxcon (https://imaginativerealism.com/), a fantasy/sci-fi art show in Reading, PA. (Along with Julie Bell)

He's a genuinely likable and modest guy. I remember a panel he was on some years ago where the discussion was how to break into the illustration market as a new artist. And more than anyone else on the panel, Boris just seemed to get it. He'll tell you about how he had to get himself established coming from Peru with nothing, and it's kept him humble all these years.

Cool guy.

Edit: Fixed country of origin, Thanks!
