I own a factory pantographed De Rosa with Super Record. While your art is 'in the style' of the factory engraving/panto-milling, I find it to be extremely well done.
I do not care for the engraving on your chrome front derailleur outer plate, but that's just my opinion.
I take it you are using a CNC mill? Very clean workmanship and the paint fill looks great.
A little 1970's drillium work might be a nice project for you.
