I want to see you progress Joe, so I'm not being critical.
A good wrap job, be it linen or leather, should be EXACTLY on the same plane as the rest of the cue, ie, no step.
Blindfolded, you should not be able to detect a difference in height, only texture.
In this particular case, you should have cut the wrap-groove deeper to accommodate the wrap.
You can't make the leather thinner so you have to adjust the groove.
This is common procedure with leather wraps because they are never the same.
In all honesty, they can vary in thickness from end to end also.
If you're going for perfection, you have to go the extra mile.
