Having only just discovered the artwork of Thai-born, london-based Niroot Puttapipat, it must be shared! I encountered it first via the Folio Society's Myths and Legends of Russia, by Aleksandr Afanas’e.
See the rest of the illustrations here, and Puttapipat's artwork for Jane Austen here, for The Rubáiyát of Omar Khayyám here, for Andrew Lang's Red Fairy Book here, and for much else here. It's beautiful work, with a delicacy of touch and incredible intricacy that really appeals. The coloured work at those links reminds me of the best of Arthur Rackham, while the Russian legends shown above have the same beautiful and sinister appeal as the work of Vania Zouravliov's, whose cover for Vintage's edition of the Grimms' Fairy Tales I love.
