I draw my sparrow female character just under the waterfall in winter and I draw this art in 2007. on this time I try to draw the same place with different characters and seasons, and this is a winter version. I think the color on the winter tree and rock become deep and the color of water looks more cold to make the severe winter, and it help to depict the character's feature.
this is the spring version[Link].
this is the summer version[Link].
this is the autumn version[Link].
