I saw this on some random site and I had to track it down to say: Insane! I can only imagine what it would look like in real life! The sound that it makes, movement, it's weight etc.... my brain is still processing this image!
Woa, it's rock! Did you manually model each detail in that numerous detail mecha soldier or you do some technique else (automate task or sth?). It made people feel it take very long time for manual modeling!!
