I like the lighting in this very much, for the most part. Almost everything looks perfect, with only three tiny sensor dust spots, and the black card tops showing their reflected height just below the surface of the drink...I think taller black subtractive boards would make this a little bit better lighting set-up. The glass is fairly tall, but the black subtractive foam cores on the left and right are not quite tall enough, or large enough to prevent the white/black juncture that forms at the top of each black board where the brighter light suddenly meets total blackness.
I really love those delicate highlights inside the rim of the glass! Those add great shape and dimension clues, even though they're small.
One small issue I can see when I scroll up and use the top of the screen as a level is that, while the glass is sitting straight up and down, it looks like the camera might be positioned just a little tiny bit out of perfect alignment to the subject. Looking at the outside radius of the glass rim and the outside radius of the glass base, if you scroll the image and use the top of the browser's hairline border, it looks like maybe there's a tiny bit of distortion of the actual SHAPE of the glass, probably due to using a fairly short lens from so close-in, and things not being quite perfectly aligned. Not that this is something to worry about in a lighting exercise, but the shorter the lens focal length you use on a round item like a plate or wheel or bowl or glass like this, the more actual shape distortion you can get, either deliberately, or accidentally.
