I have a bit trouble makings sense of what it is. The stomach area especially. The pants are sort of paper and they fold into the ribcage? The face too, is it a robotic face? What's going on with the shoulders? Even though it's a pretty warped character, you should hit the books and check out how things attach in a humanoid body. There's definitely some good ideas behind this, but it's having a struggle trying to make others understand
I like how you did the clothing. There's loose cloth and there's tight cloth, which makes it more interesting to look at. Give a thought or two for posing this character. It's a menacing one, so what makes a pose scary? Just doodle some stick figures and try and make it relay information with the pose alone, then come back to this character and add whatever you learned. Oh and, just for the sake of practice, do show his feet, or at least plan how he is standing.
