well, this is my first mech so let me know what you think. it doesn't have a lot of weapons besides the heavy guns on it's right arm and the light guns on it's left arm. the wrists and shoulders swivel. i had a problem with the legs because of the weight of the body so i had to lock the legs so it wouldn't fall forward.
I like it, it looks chunky and has a good style, but it looks more suited as a construction mech than a combat one. If you can refine the joints a bit and make it more stable you'd have something really great.
