You don't need a paper background on this one Toni, the white wall & base work really well. The bottle looks very good, the colours on the flower have blown a bit, but only in the centre, but then I think this sort of hot pink always foils the camera sensor. There are some reflections in the glass, but not many & not distracting, you can always drape bits of black material to the side to cut them, I use some old t-shirts or any black clothes.
If you want the flower standing higher in the vase, wrap a bit of kitchen roll round the stem & wedge it in the top of the bottle.
On the whole though, I really like this one, the blue and pink really go well together & the bottle is interesting.
