Very nice. The edges on the flask seem a little sharp however. In reality, no edge is ever that razor sharp. Try putting a slight bevel on the edges to chamfer them and allow them to catch specular highlights:
eg:
See how the cylinder on the right catches the light better than the one on the left. The left cylinder was just a normal Lightwave cylinder, the one on the right is identical except the end cap has been bevelled 3 times: one with a small shift, then with the same shift and an identical inset, and finally with no shift and the same inset.
