Also note that I've calibrated all of my lenses and the 50 was the lens that needed the most shifting than the others. It wasn't significant.
Your test shot looks good and pretty standard from my experience.
Congrats on the new purchase and enjoy learning your lens. I've had mine for a while now and using F/1.2 is still a challenge. Apart from that it's a great multi-purpose focal length that should provide you with many great images in the future.
