I would like to express my deep appreciation to the editorial staff of the Digital Art Live magazine and David Haden for the publication of the article with my interview with my artworks. The article devoted to my sculpt of Elon Musk wearing Tesla Cybertruck clothing and also containing my other science-fiction creative works. The issue of December 2020 is a tribute to Elon Musk and its contribution to all humanity progress.
