This adorable little miscreant is a Kobold Smasher from the Fenris Games Toadstool Brownies Kickstarter that's currently going on. For full disclosure, I was sent him free as a promotion for me to paint up for the blog, along with two Brownies I haven't finished yet because I am a slacker.
He was a single piece metal model and needed practically no clean up whatsoever. I think he's taken paint really well - I used a mixture of Contrast and traditional paints to get him done. There's only a few days left on the Kickstarter campaign, so if you have the free funds, please do head on over there and back it!
