I like how it looks, but don't you think that little bit more light at
the bottom will enhance perception of material and shape ?

It's up to you, no doubt, but I only wonder how did you get 168 Mb ?

))), understand, here is a version optimized by ZBrush retopology algorithm:

Here it is. Also increased the light intensity a tad (personally, I
prefer the darker version where the surroundings are less visible)
The optimised mesh has the same quality as the 'heavier' one. Well done!

I like how it looks now, but this is your project - your rules :)
And don't you think that it's time to animate it now (putting on
turntable first) ?

This is Pixologic's magic, not mine :)

cheer away :-) link to 6.1M zip, 17M mesh. looks unchanged, afaict. (started
playing with a rose quartz material, so sample scene is .. untidy)

Analysis of the provided mesh is a work in progress.
All measurements are in the Imperial inch system as stated by the metrologists
Alex Dunn and Nick Sierra in the video.
Therefore all <x, y, z? vertex coordinates are in inches as well.
The original mesh is roughly center-of-mass with the top pointing in the -z
direction.
Height is 4.72 inches
Radius of body is 1.67 inches
Still working on establishing a center axis and radius for the lug handles.
The measured data points only extend so far beyond the surface, making the use
of trace {} difficult.
Once that is established, next would be the
best-fit sphere center and radius for the vase body
best-fit sphere center and radius for the vase lip bottom
best-fit cone and radii for the vase bottom

neat. when I use the 'vase_3.pov' with shadowless lights and explicit no
reflection on anything, and use a srgbft pigment (like yr recent "gyroid"
thing), I see interior "features" too.
