Wood? I don't see any combustibles. The textures look great as does the fire. May want to scale down the brick size inside the fireplace. They're traditional style bricks but on a bigger scale than the outside and it throws the eye off a bit. The inside is usually fire brick(heat resist) and the outside dress brick(standard), normally the same size. Occasionally the inside will be fire block which are less rectangular. Nice work, Keep us updated. ICM
