don't know if you're looking to include my entire gallery of changeling pictures or just concept pictures. in any case you can double check here:
siansaar.deviantart.com/galler…plus the commissions folder if you want.
siansaar.deviantart.com/galler…commissions don't necessarily pertain to my own headcanon, but i think that's irrelevant in this case, no?
as for the ocs, sure, why not?
