Mini-hint #A1

Whenever you are preparing a cuspid, it is easy to lose track of what you have reduced, and the most common error is underreduction.
The problems are not total reduction, but more in the 2nd and 3rd planes of the labial reduction.
First, I would HIGHLY recommend cutting pilot grooves on all anterior preparations, but, if you insist on freehand, just be aware that the DISTAL 1/2 of the labial is the most commonly under-reduced (simply because we can see the mesial 1/2 better.
