I draw my bat boy character Kuraresu with a bat wing like umbrella and I draw this art in 2011. many years ago in Japan, the umbrella is made of the bamboo tree and Japanese paper, and after this typed umbrella appears and people say it's bat umbrella because it looks like the bat wings. in that time I draw on rough paper and I think the color isn't good, and now I feel the small rock mountains are too simple and a few messy and the it have much yellow color, and I want to draw the bat and the umbrella art.
