Hi Chip,
I agree with jC and Nathan in that it's all in what you like. I've noticed myself cropping into squares with alot of shots lately. Some of my best friends are squares shots.
Also am doing more 8x10 (whatever the ratio is).
Hope you don't mind that I recropped your shot to 8x10 ratio putting the faucet knob center at the upper left third. Nice shot you got there, btw! Love that crisp, clear drop with lovely blues in the background.
Debbie
