For a second horn, not bad at all. I concur with Mark's comments regarding the engraving, but I'm not the expert on that phase,,,,,,yet.
Seriously, the overall effort is very good and only more practice will demonstrate improved techniques. Keep up the good work.
And a great idea to honor your Dad's contribution.
