Here's the third Celestial Lion. I consider him the most impressive, although that's probably because the most work went into him.
If you aren't familiar, The Celestial Lions chapter are known for loudly criticizing the Imperial Inquisition, an being largely destroyed as a result. For that reason I knew the sergeant needed a special sword. This sword in fact. I thought it'd add a fun bit of character. (Don't worry about the Inquisitor, he borrowed a sword from Mephiston)
Overall, this guy is my favorite from my Lions. Someone even posted him on Lexicanum for the Celestial Lions while he was still a work in progress. Maybe now that he's complete I'll have to see about putting him back on.
