As ever, the photos aren't terribly good, but I hope you get the idea...
The barbarian is from a Kickstarter that Oathsworn Miniatures did back in 2013.
A particularly poor photo, I'm afraid, but she's 'Olivia' a Reaper Bones' Apothecary/Cleric.
Ral Partha giant stag beetles. Not much more to add to that.
And these are from Lucid Eye's Toon Realms range. Quite nice range if you like whimsey.
