Hey spidey, nice work. It's got a nice energy to it and you did a fantastic job on the metallic texturing ! There are a few anatomical errors though, for example his right bicep looks a bit on the small side and both his hands look a bit strange ( not too sure why but I wish I was because I hate giving crits and not being able to offer helpful solutions ) but yeah, his hands both look a bit strange.
Other than that the only thing I could really suggest is playing with the line weights a bit more. Overall it's a great entry and it's about the most accurate M3 movie version I've seen so far. Great work, keep it up !
