This is [**Children of the Corn III: Urban Harvest**][1] from 1995.

>Two brothers connected to the murderous children's cult of Gatlin, Nebraska are taken to Chicago by an adoptive couple.

One of the brothers is evil and kills people supernaturally. And you can see the scene you described below - the kid drawing, the low angle and the woman spooked by it (it's a vine that comes after her), her falling on a pipe and the water coming out of her mouth, it's all there [WARNING: NOT THAT GORY, BUT STILL A DEATH SCENE]:

*[BTW, this was Charlize Theron's first movie (they all have to start somewhere, I guess). And BTW II, this scene was possibly inspired by [a very similar death][2] in 'My Bloody Valentine' from 1981 (WARNING: GORIER THIS TIME).]*
