this one here is a nice view on a teacher cartoon. Good background, simple.. but gets a point. Her smile and glasses are cute and drawn out well. The details in the hair is good...the texture, shines, shadows, and overall color is great but the girl needs a bit more work in her hand the hand just seems off psychicaly so id try to focus on that aspect of your characters more. gotta love a teacher with a kill list...
~~THINGS TO IMPROVE ON~~
Just work on the way you draw hands and that is really all i can say
