Things I changed: adjusted his skin to be more specular added scratches and adjusted material to the sword guard rotated him so more of the sword was visible edited the ground shadow edited the comparison sheet new ambient occlusion render
I reposed him, he's a little more twisted and balanced. I retextured his stomach so that it is more representative of the belly of a crocodile. with larger yellow scales as opposed to the noisy blue scales. I added a bit more muscles/abs to fit with anatomy but I'm still not sure it's what you're looking for? He's floating, and doesn't have his sash in this render, but this is just to show the change's i've made
