A free series, just like the galloping and trotting and pegasus series.
They can be used on deviantART however you like.
(Not on other websites, please
, because it's impossible to keep them from getting stolen, un-credited...)
They can all can be viewed and downloaded freely from here: sta.sh/216snkvugk1p
I'd rather not host them all in my gallery any more, as there are just so many
and it got very cluttered!
Sorry, I no longer make these avatars now.
If you want a custom-coloured version, you (or a friend) can use the plain White one as a base to edit.
