Been messing about with some mussel shells
Couple of white fibre boards, flash hanging on radiator by a Joby GorrilaPod and triggered by an RF-602
I like this in theory... I definately think it has a lot of potential. IMHO the shadows are a little harsh - have you played with a softbox for your flash yet? May be just the ticket.
Also, there are some small black specks that should be cloned out...
I do think that the colors and comp are fantastic!
