Thanks for all comments.
It IS based! ;P
here is better photo (I think )
yes, I know, it is sh1tty simple, but I think it will end on some battlefield with redone base, rather in cabinet
here is also more visible to see the difference between flame and rest of figure, because it is painted with fluorescent paint
On the other hand base looks better IRL - it is painted with metallics, so it is hard to do good photo.
Or should I rather paint figures too look good on auctions? what do you think?
