Andrey Mamaev's realism is very much in the Russian academic tradition and unapologetically romantic. We have all seen so many bad examples of this kind of art that it is sometimes difficult to recognize when it is done well. I don't have much more to say on the subject except to emphasize that you really need to click on these images and view them larger to appreciate the almost calligraphic fluidity of his technique. The size is not indicated on these pieces but most of his work is surprisingly small.
More of his work, and lots and lots of great details, can be seen on his Flickr page.
