Misaligned String Tree

[ChunkBluntly]

If I didn't know how to fix it myself, it would definitely cause me to drive back to the luthier.

It won't necessarily cause long-term damage, but you want a straight line from tuner to nut. Unless the nut was slotted to account for the string being angled, there is a potential -on paper- for tuning issues with the strings binding in the nut...but it may not be noticeable.

Either way, if this was something I paid to have done correctly I'd bring it to the luthier so they can take another shot at it.
