1/6 is generally a good, manageable size for someone astride an animal or a machine.
OTOH, even though I was initially more interested if this were smaller and less expensive, the more I look, at it the more I would be just fine (prefer?) having it run close to a smaller PF size (22"-25" inclusive of the base) and with that equivalent price tag. It definitely doesn't appear to be that tall, though.
In any case, it would be a nice respite from displaying almost nothing but superheroes, Star Wars, and cheesecake.
I would have been all over that House Of Gog release, which was also based on a previous illustration and channeling a similar funky/cartoony alien world vibe, with even more striking colors - but not for over the over $800 with shipping they're asking.
for reference, here's that one (it's 16" for the figure, 19" if you display it with the moon backdrop)
