I really like your sculpting, in the past I made some 15mm commissions so I realize the work it represents. I believe you found a good balance between "readability" and details.
I'm not sure LAF is specific to a scale, you can find plenty of diferent sizes here, from 6mm to 54mm ! Perhaps some periods/thematics are more "compatible" with several scales (15mm and 20mm for WW2 and modern, 28mm for dungeons, 6 and 10mm for massbattle fantasy, etc...).
