Here's my only effort to date:
The blank was off centre and I wanted a simpler scroll at the top. I looked at my other guitars and none of them had a chamfer on the headstock so I added one.
The logo was a laser printer > packing tape > soak off in water job. Only thing I'd do differently there is apply it much sooner in the oiling process (say after the first half dozen coats).
Got a more complicated plan burgeoning for the next one.
