The concept of realism is good, but Kratos stands out too much so you cna see it's a manip imo. His general postures can stay more profound as it is but it's mostly the tip of the sword that stands out too much for me. Also because of the blurred dude in the back so that would make it seems as if he's pretty far off while, looking at this sig, he actually seem pretty near.
Looks alright Kinda big for my taste but I think you should try to blend the render a bit more.. it looks like it was just pasted there
