The reality of it is “ALL YOUR VCARVE ARE CREATE TO FUZZIE”. Soft wood fibers want to bend first rather than shear when hit with a cutting edge.
So everyone has some techniques to minimize this effect, with consensus on twice-carve.
I carved this tree trunk on the back side of the same pine piece, so I could hit the same grain.

It seems to me, the slow feed rate (20 ips) eliminated most fuzz, (in this case) but still has that bludgeoned look in spots.
I filled in with shellac, dried for an hour and reran the same toolpath.

A slight improvement; for me it’s acceptable in this poor quality pine, so should be just fine in a better species.

Thanks to everyone for sharing your solutions, reading this forum has spared me from many frustrating rookie mistakes; I’ve actually made some stuff that’s ‘not bad’ for a beginner...
I will keep in mind also sharp measured tools and good quality vectors when striving for a ‘pro’ look.
Same as - really nice response on the learning experience.

It's always nice to see how a poster has completed the analysis of a problem.

Thank you - from another poster
