Illy cups

As per my other post (Bronica), I was playing with the flashes to try to get some 'high key' type shots of my illy cups.
I would appreciate criticism on how I can improve the lighting set up.
Basically, the Metz was on the tripod pointing down on the cups (with a diffuser) and the SB800 was on camera (with diffuser).
I was trying both shallow and larger depth of field, although not sure which one I prefer.
C&C appreciated.
I took a bit of creative license with the last one by desaturating all but the middle red cup.
Cheers
