maybe a bit more "outboard" than many, but if your mechanic matched the spindle taper to the crank arms, then the important distance is between the cranks at the pedal ends and the chainstays: you want both sides to be equally "outboard" and so balanced when you pedal. You can just eyeball those distances but also very easy to measure with any ruler or tape if you have doubts, and if within a mm (or two) for both sides it's acceptable to most of us.
If there was a screw-up and you have the wrong (too wide) spindle length or the wrong type (could be symmetrical when you need asymmetry) then get your money back and find a better mechanic!

Also: how's the chainline with this crank and BB? Did mech-o at least get the driveside right?
