Nice and clean. I think you can add more scratches in areas like the top of the skull. This prop has an nice overwatch appeal to it in my opinion. You didn't make an book prop in your concept so I just don't know where you'll be adding it, but it looks awesome. Did you render these shots in keyshot?
Cool material. Reminds me of the overwatch characters. Did you make it yourself? If yes, let me steal it 
Keep up the good work man.
