Looks pretty good! Few notes I’d add are that the swords are in a quite bland and basic position, somewhat weird looking (especially for the guy on the right), but the lighting as everyone has added is phenomenal I’m amazed by a first time GFX render having such amazing lighting! For positioning I’d recommend getting into R15 studio positioning, it gives you a lot more joints to work with - if not you can always use Blender to add bends to R6 OBJ files.
One other thing I’d add is that there is quite a bit of negative space. Are you aware of FOV? What a lot of GFX developers like to do is create the illusion of FOV to make it look more zoomed, detailed, and fill unneeded negative space. If you’re not sure what I’m talking about it can easily be added into studio using an administrative command script or default studio settings. I’d recommend trying that out with the camera angle. Otherwise, I love the background and the render quality is amazing! I hope I get to see more of your work in the future.
