He's the "Salamander with Sword and Shield" from the Dungeon Degenerates Monster Miniatures Set. Despite the name, he looks like an overgrown Lizardman to me and not the classic D&D salamander.
These figures are ostensibly 32mm in scale but seem like they might even be a bit bigger than that. This fellow is on a 40mm base. Here is a picture comparing him to a D&D pre-painted miniature for an idea of scale.
I'm pretty happy with how he came out and I plan to paint the three remaining figures in the set shortly. Fun miniatures with a lot of character. Stay tuned!
