The gun reminds me of the M41A pulse rifle from Alien; I love that gun. I also like the gold trim and decoration on the armor, it makes me think of Roman soldiers or maybe Medieval knights, all while still maintaining the futuristic look. And one more thing to add, the soldier's tough, 'I've-been-through-hell' sort of expression contrasts perfectly with his armor's polished look. Excellent work, 10 out of 10.
And Nemexia is also a nice browsergame, although I haven't enough time for this game.
