your getting better with every work. thats obvious. nice excecution. not too much detail overall, good use of the tones and i especially like the weapon designs. they have a realistic touch and yet look futuristic. thats where many designers fail, when they blast in so much detail as the can. maybe you still have to get used to some more proportion rules but thats a mastery that comes with time and excercise. keep on rocking dude!
