this piece of art depicts Sans about to fight the Chara, His battle bones ready to be
fired like bullets. The shading is well done and indicates that the sous are glowing. sans's anatomy is very good but the hand needs a bit of work. I also fell that Chara looks too two dimensional and lacks the epic pose that sans is scene doing.
the use of the 9999 in the background is a nice touch and pairs well with Chara's
growing red eyes. in conclusion, this is a well made piece of art (with some flaws)
and i hope to see more art from Kaysa99
