Winner gets both "slots" — the the big pony and the small pony.
Small character can be pony or some lookalike only. (earth ponies, pegasi, unicorns, alicorns, bat ponies, changelings, kirins) Other races are negotiable if the winning bid ends up at $80 or above.
Big pony has to retain a pony head shape in any case.
Extra details and/or extra changes will require a markup, typically $10-20.
Primary payment options are Patreon and Boosty. Others are discussable.
