This looks magnific. I will even give you a worthless rep of mine.
You are talented.
The only problem: Never forget that the details can be found in the texture instead of the model, not just it will look better, as well as the file will be smaller. Also, the model can be less smoothy and you should add some features on his body, his muscles, or bones, or for a such heavy file, I expected the cloth to look real with its 'bendings' (Sorry bad english, hope you did understand). Try doing it.
Keep up good work.
