Sutoppu!!! Kari and Shizuka

It's been a while since my last coloration... I'm too lazy and not very creative currently... :(
I have drawn the sketch a month ago, two weeks later I finished the outlines... 
Did you know that these are my first two SD-characters?
I wanted to create two opposite characters, mentally and from their outward appearances....
At the first sight Kari (left) is the naiv and lazy one, while Shizuka (right) seems to be the smarter one who tries to hold back Kari from doing stupid things (but she really gets angry very fast). That's also this picture's motive. :)
I have also a non SD-version of both, but I've only finished the sketch until now...
