Amazing detail, it actually looks like one of those video games sketches for what it is going to be, I believe you have a wonderful gift, I think (if you don't have one already) you might have a shot with amazing video game companies like Bungie, Bethesda, or Ubisoft. This artwork actually reminds me of some sci-fi games like Halo or Destiny, I really like the digital detail put into it. I like that it is proportional to a human body and that its realistic.,I think that you also did a good job on the weapons and torso, it really pops out with detail.
This is an amazing piece. Your understanding of the human figure, specifically the human male, is very strong. This is strengthened even more due to the relationship of the proportions of the various pieces of the suit to the subject's natural body. The extensive amount of details on every single inch of the subject and his suit is awesome. I can definitely see elements from Dead Space and Mass Effect 3 in this piece; in addition, I see qualities usually present in concept art for the Halo franchise. It is plain to see that you are capable of presenting powerful and interesting artwork in a very creative way, and I hope that your skills become even greater in the future. Keep up the good work!
My only concerns, and this is from a design standpoint, are the forearm and shin areas. This is just some personal OCD (The artwork is amazing), but those two areas seem slightly off-balance with the rest of the piece. Like, maybe if you had slimmed them down a little, it would have flowed even better than it already does.
