Iam Not Defending the Taxidermist,but having mounted thousands of animals in the past 40+ years, that is a young buck and he must have being afraid of damaging the tender bone.
The broken antler burrs are easily recreated with sculp all epoxy and stained no one will be able to see any defect.
the only thing that needs to be improved is the yellowing in the skull joints, that needed to be cleaned up as it still has fat in it.

But enjoy your trophy it is all part of learning.
