The Xtal sits crooked, bacuse of the pin size mismatch.
The pins on the xtal are maybe 0.4-0.5mm in thickness, and the holes in the PCB is maybe 0.7-0.8mm - in that case, it can be turned a lot around, and still be soldered in perfectly. It does not matter in any way!
Look at other boards, it's quite common for some components to sit very crooked.
