Baxter, this is going to get interesting!!

I love all the colors - particularly the blue/green combos, but that wasn't what you wanted to hear about! I think my view on vase forms is influenced by an overly structured attitude about many things (there are names for that condition, but we will forego those!) For that reason, I am drawn to forms that approximate a parabola or catenary in the lower body. In the sketch below, the parabola is blue and the catenary red (but, then you are a retired school teacher so you know all this!!

In the first pic of the grouping of five, IMO the second tall green vase comes the closest (but I think the shoulder is too high), and the fourth green/blue combo is a close second (because of the better (IMO) shoulder placement, I like this one best.) For my tastes, the others are too heavy in the curvature.

But, I think you will get positive responses for most all of them as it seems to be a very individualized preference thing.
