You have the makings of a very nice shot. The Fostoria glass is a beauty, especially the blue color which is made to order for this challenge.
Compositionally you have a few things you may want to look at. First, the glass seems to be leaning a bit to the left. I find myself being led to the berries on the left of the photo and IMO they are a distraction. The item on the right is not really identifiable and out of focus and also serves as more of a distraction than an addition to the shot. Both of the items are casting unwanted shadows on your background. There are also a number of light glares in your glass. I count at least 12 which is also distracting. You may want to try a shot where the shadow of the blue in the glass shows on the bottom of the shot. It is a bit cluttered as is and takes away from your focal point.
The blue glass certainly meets the challenge and I feel with a reshoot and a few new twists you have the makings of a really nice shot.
In my opinion the two things on either side of the glass are nothing but distraction. They are crowding the glass and fighting it for the attention. One is actually touching it. And you cropped part of each off, as if to say they don't matter. If they don't matter, don't put them in. Left out and the glass more centered, this would be a beautiful shot of a beautiful piece of fostoria. PTL. 5
Nice still life. The plastic berries are a bit distracting and don't really provide enough of a contrasting color to the beautiful blue in the glass. Positioning this further from the background would help in two ways: the shadows would not wrap up vertically, and the background detail would disappear and become more of a solid white. Good shot. muckpond
could be straightened just a little, i think. i would have also muted the other colors besides blue just a little. (nothing drastic) the decision to no include the entirety of the other objects was a daring one, and i think it worked. the placement of the glass was good. 6
Pleasantly lightied, with a nice background and clear focusing. Personally I don't care for the choice of added colors with the blue, as they seem to clash, but it's a well done photo.
