It's hard to tell from photos. It's looks wrong in many ways but most of that is camera angles, because it looks different from one photo to the next.

I think your best bet is to get a yellow legal pad and a yellow tape measure and start measuring corner to corner on everything you can find. You'll find out what's wrong soon enough. Anything within 1/16" is "perfect". Anything within 1/8" is darn close. If you start getting 1/4" difference from opposing corners I'd really scrutinize those dimensions.

Sometimes it's just bad luck of a lot of in-tolerance things adding up to out-of-tolerance, but I'm going to guess you have a more serious misalignment.

Edit: Those are just my own personal benchmarks for placement accuracy. Not from the assembly manual or anything official.
