Simple idea, tons of texture...
Ok, so minus all the sheepskin and cowhide upholstery, I dig this look, and it can totally be DIY'ed at home. For starters, the antlers on the wall are wooden plaques (which you can get at craft stores like Michaels) with some fall tree branches. Easy to make, and a few of them covering the wall will look like an installation.
Now, for the firewood rack: If you have a large space that seems pretty empty (and you don't want to spend tons of money on furniture) this'll fill 'er up . You can either stack the wood from the floor up and attach at shelf at the very top OR you use 2 shelves: one at the bottom with enough grip to hold the weight of the wood, and one at the top for storage.
Oh, and you don't need to use a whole log, you can actually cut them in half so they don't stick out too much - and if the space is too narrow, just cut a few circles (like coaster-size, but a bit thicker) and glue them all together so it they create a faux firewood effect.
