Looks good! Interesting based on the replies, everyone imagines this at a different scale... One constructive critique... The water seems to have rounded edges inside the glass which gives it a meniscus appearance (like mercury does in a tube...) If this is very small scale, that might be accurate for a liquid metal like mercury, but water usually has a concave rather than convex meniscus. If it's a large scale item, the curve would be so small in reality, that simply making the top flat at the edges would have the right effect. I think you can improve the water texture also but you might have to make two objects - one top flat disk and another cylinder for the sides. I think the recent water tutorials really apply to looking at water from the top. The texture that you've used on the sides makes the water look very turbulent. It's actually a cool effect, and might work great in a lava-lamp type thing (maybe even with different colors!) One last tip - just before you're done, edit the glass reflection map - that's the standard P5 one, Just make something in photoshop (or similar program) that looks somewhat similar, but is a bit varied (so that your map is unique).
