Me too, Blok is my favourite Tolkien illustrator, and Tolkien himself appreciated them too.

This is a great book that reproduces all his artworks available (a few are in unknown private hands):

Oil pastel drawing I did along with my advanced art class. The task was to create a quick collage without a preconceived plan, then upscale using oil pastel. My subject is Daniel Home, a medium/spiritualist from the 1800s.
