The table is just brilliant. Absolutely flawless. The wood is worn enough that there is texture but not so over-detailed that it's distracting, and the light is done brilliantly.
I like the glass, too, which once again serves its function without being too ostentatious. I'm not certain about the little glint. I think that can be taken or left.
The 'blobs' of milk are really well done. But the main milk... I know you're keeping the color count deliberately low but the gradient still seems very abrupt. Maybe it would even benefit from fewer colors? And with a bit more lighting to the left (where the source seems to be.)
Also wanted to say: I really like your gallery, and you're waaaay better at this than I am, so I hope my feedback is useful anyway.
