Re the Facebook shutdown I’d suggest establishing a presence on some older forums:
The Miniatures Page
BoardgameGeek
and
Consimworld
all of which are smaller and more approachable than Zuck’s monster, but also with a clientele who will find your work of significant interest.
I'll take a gander at BoardgameGeek and Consimworld, thanks! TMP is certainly a reasonable option, but of course take a dim view of "advertising." I ran ads with them once, but when I returned to try do so again, couldn't log into my account... tried to get in touch with Bill perhaps three times to ask if I could have it reset and he never replied >.<
