I would say that the flash mounted on the camera in combination
with a very close subject makes the flash emit most of the light
above the subject. It's too bad that the 420EX (I have that too)
cannot be pointed down. Mounting the flash on a bracket on the side
of the camera pointed directly at the subject would be better. I
would even try the pop-up flash, wich I'm using myself often (since
it's there) when shooting macros. I do not know if the 100mm Canon
blocks the flash when shooting close subject. Even at 1:1 with the
Sigma, the pop-up flash is not blocked. Can you try that? I.e. take
a flat subject (table cloth maybe) as close as you can with the
pop-up flash and see if the full frame is evenly lit?
You could also try installing the "russian-hack" and bump up the
flash exposure compensation, maybe?
But, you're not wrong otherwise, F/13 and ISO 200 are both
reasonable. And 1/125s is also not a bad choise, lower and shaking
is a problem.

Please tell me what I'm doing wrong? I've tried same settings as
many people on this forum who got great results, but mine sucks so
bad...
