Floral arrangement is pretty, but there is an obvious gap between the top of the vase and floral bunch.  It would look less 'fake' and more full/real if there were more leaves/greenery at base of arrangement.  This would help 'fill in' the visual gaps to make the overall arrangement appear more full/lush.  I have placed the entire glass vase in a white ceramic plant holder up to the leaves/foliage, so the arrangement looks much better now.
