Good stuff.

My technical note is on the perspective. Most notable is that the ellipses don't follow the perspective. The most glaring is the base of the glass which you have as a straight line as if the eye level is right at that level. But as you can see from the planks of the wood table that the eye level's much higher.

When you're doing something as mechanical as a glass, mechanics or perspective are an issue. You can get away with a lot when doing organic subjects as with your snow, which looks fine. But it's a bit more ambiguous. In the case of a glass of beer perspective is a big feature.

You did better on the ellipses in the upper part of the glass with the head of the beer and so on.

As to the textures, it works nicely. It's feeling wet and frothy. The reflections on the smooth glass has a different character than the wet foam, which is different from the amber beer. All that is nice. As to the wood grain, it looks like you weren't paying much attention to it and quickly knocked in some lines like a mental note that there's grain there.

Anyway, as experiments and stretching into new subjects, this is pretty cool. Nice foray into the lesser known. It's a bit amusing to me in that there is an old advertising slogan for Miller Beer: When it's time to relax. . . If you've got the time, we've got the beer.

Looks like you had the time and produced the beer.

Well done.
