Jack I congratule you for these great steps, actually I am doing also my own first tests with this technology
I agree totally with your statements.
I believe these printed models of you are "shots" somehow taken from models un Warhammer Total War videogame, nice find!!
For instance I Bought also some 3d figures from Speira, I found they are autorized files from 3d Creator Artisan Guild, let me also show them to you all as comparison.
The printer allows you yo adapt the scale ar your choice...not always the details Will be the same, but scaling from 28mm to 1/72 comes easy..
The Speira product were crisp and match so good with 1,72 comercial plastics (and look even better st some point as Jack said)
However, By Next example which I tried to print on my own I Ran i bit out of scale...I trusted the total height but did not care of total actual proportions..these dwarves are Big headed and Round bodies!!.I Must repeat at smaller size...Size of head is the most important human reference point.
