I agree that the goblins are nice and the troll has too large a club. I think it's the part it's holding that bothers me, feels like it couldn't grip the club properly and it would be awkward to wield.
and another one, Skrohll the venerable! This old Goblin likes nothing more than collecting (or rather stealing) books, scrolls, or any kind of papers, although he generally loses interest once he gets his hands on them, and moves to the next one. He may not look very dangerous, but don't underestimate him, goblins don't live to be this old without a few tricks up their sleeves!
The Troll's well sculpted but pretty generic and his pose is a bit static, but those gobos are full of personality. They've got a really classic fantasy vibe to them, like an illustration from an old fighting fantasy book or the goblins from an 80s fantasy movie or something. Just the right balance of comedy and menace. The wizard may be a bit stiff but on the whole they're very dynamic and characterful. Great job.
