For me this inversion of positive to negative does nothing to enhance the picture or to highlight the qualities of the glass. I actually prefer the original positive image.
the details and neat, esp. in negative, although the composition seems random and why did you take this on your lawn? the grass and the rough texture at the top left just seem strange and distracting.
I find this picture lacks an interesting focal point. The busy background also takes away from the picture. I'd like to see either the subject on the left OR the one on the right alone. Jacko.
This composition is interesting, as are the patterns in the glass. The only thing I don't care for is that the whites in your background are really "white" and it makes the glass color of the subject actually look a bit grayish - takes away from the interest of the subject itself.
Nice composition--placement of objects is very engaging. There is not much contrast between the glass and the background. I also wish the glass were as lovely with light as the background.
