Andrei was best known for his outstanding miniature creations in 54mm and larger. When I first started painting figures back in the mid-1990s his "Eye Deep In Hell" was for me one of the best examples of modeling and painting I'd ever seen. He wrote an article about it for Internet Modeler back in 2001.
You can see more of his figures on his personal web site.
Andrei was also an accomplished aircraft modeler and was particularly adept with bi-wing aircraft, which as we all know are extremely challenging and require an almost engineer-like prowess to master. It's incredibly rare to find a modeler who excels -- and I mean truly excels -- at more than one area of our craft, but Andrei did. For that reason alone he will hold a special place in scale modeling history.
