I decided on an off-white for the background in the end, but I'm not that happy with it. It looks very messy, and because I used dark grey and silver for the twig it looks a bit like pencil - v. smudgy!
I'm working on this for a friend. She wanted something black/charcoal/silver/white with a splash of vivid pink. Trouble is I can't decide what colour to do the background, I guess it's either black or white - opinions please!!
(ps, flowers aren't finished yet, so it still looks a bit crap I know)
