I think its way too bright and over contrasted in parts. A lot of detail on the render has been lost as a result. The render looks a tad blurry too and I found it pretty hard to make out what I was actually looking at. There are some nice effects in there, but I think they need toning down a bit imo. I'd give it a 6/10
Still too bright around the Spartans arm and head, try toning that down a bit. v2 looks the best 7/10
