Thanks for the positive comments, all.
My understanding of "soft custom" comes from Garden Wargaming. Basically, it is that klickies don't have any custom painting, printing, moulding, etc. on them and that one uses only Playmobil parts with no modifications. Perhaps, however, I'm mistaken and using this term incorrectly?
The kings, queens, standard bearers, signalers, and traders have all been disassembled and are not completely original, but most figures feature their original torso and legs. I've only modified small items, such as weapons, belts, cloaks, facial hair, headgear, arm accessories, etc. Although these are relatively small changes, I think they make a difference, which is why a former Roman is now, say, a Parthian. That's what I love about Playmobil! I've put a lot of thought into these, and although they aren't revolutionary, I think the result is pleasing.
