I draw my demon boy character Yarmu with digital media and I draw this art in 2008. in 2004 I draw this character with same cloud background and I redraw it with different media. I feel the colored pencil is easier to use. the color become colorful on character, and I add the perspective effect on the cloud and it become good.

this is the 2004 version[Link].

this is the 2019 version[Link].
