This is one of the Chibi miniatures that Impact! Miniatures has been making of late.
This is one of the earlier ones that they made.
One interesting thing I discovered while at Gencon this year- Trollforge (the guys responsible for casting these minis) has been upping their quality quite a bit. The newer castings have a much smoother finish on them.
If you have some of the older chibis, the surface can be easily smoothed out in any problimatic places using either gloss or fine grit sand paper (I mostly use the second). But the newer ones don’t need it so much, and that’s quite nice.
Anyway, here are some images for you.
