Your soldiers seem to hold a more post-apocalyptic kind of look, as well as right after a battle almost, these soldiers look like they're dealing with a mission and also look more like cybernetic guards in an age where things have progressed, not been destroyed. There's snow in this one, and yours has fire. This one has three troops near an outpost, yours has two troops near wreckage. There are too many differences to even call it inspired by yours. Your art is nice, in fact, it's just as good as this piece, but they aren't the same.
I'm not the artist but looking back and forth between the link you posted and image this guy has done and there are no real similarities beyond genre and a lamp post placement. Your a good artist and deserve respect but get off your high horse, that was a horrible comment to make on someones work.
