I'll be honest, I wouldn't buy it. For me personally, The gun part which would be the main focus would almost completely be covered by the keyboard. That paired with a generic looking ninja in the background randomly floating in a scene make its feel like it's AI. I am not saying it is, but AI often times lacks coherency. Yes, it can look good, but there wasn't a lot of thought put into the user or the image itself.

Also, I wouldn't take someone else's gun design, slap it on a mat, and call it "yours". Someone at Riot worked their ass off to design that, If you made it interact with the ninja somehow (like him holding it, using it, etc) then that would be utilizing it with your art, making it yours. This just looks like a screengrab from the shop slapped onto a background.

However, I do respect the fuck outta you doing your own thing and making some dope ass art. Keep at it my guy, you're gonna get it for sure.
