Hi ! this looks very carefully done: the glass model has an very nice surface,
Two things that are probably due to WIP and not activating features during this
stage, are

a) From afar, the brightness seems sligthly off... as if the
texture-to-lighting-to-final-image gamma was somehow too high ...doubled? / not
reverse corrected as should happen in linear workflows allowing best contrast
preservation or maybe a media is at play in the room?

b) Then opening the image at maximum size... Doesn't the anti-aliasing look to
be off? or too low? Is it Method 3 and/or no AA value combined with a camera
aperture? Where this shows most is on edge of the glass where some kinds of
fireflies appear.

Are you using a branch, or vanilla 3.8 pov? I would be curious to know the
render time.
