Sevilla,
Not 100% sure on the pine bowl, the angle of the photograph might have something to do with that though.
The vase on the foot works for me. I can see what the others are saying, but it's too tall and thin for the base diameter, it would be unstable, a slight vibration or breeze and 'Ooop's' over it goes.
The foot (either) has enough interest to act as a counterpoise to the curves of the vase and gives it even more height and with that (and the thinness) more elegance.
