I draw my bat boy character Kuraresu with dark breeze background and I draw this art in 2021. in recent year I start to use the black colored pencil on the outline of some characters and the rocks, and on this art I mainly use the black colored pencil and it's monochrome art. once I feel the single color art is difficult and it show the art skill much, but this time I enjoy drawing and I don't feel the monochrome art is hard, the breeze effect is really fun and the single color make the shorter time to accomplish, I'll draw more monochrome arts.
