Hi guys ... thanks for the feedback ... I like (slightly, intimately) backlit objects but have been told before about them looking flat, so must bear that in mind.
This was taken at home ... plastic cup on a box on top of a table, same height as the mantelpiece where there's glittering christmassy things inc. a string of tiny white lights, and a big mirror above.
The marigold inflated and sealed with freezer bag clip. What fun.
