Deadpool Headset Stand Wall Mountable

I really liked the model by @Just_Josh, but I wanted something to mount on the wall. I edited the model to sit flush against the wall and added two keyhole mounted holes. The section where the keyholes are has a stronger infill from the rest of the model to give it more strength. ***Important - I'm not sure what happened with my print, but you can see darker areas of the red. Im not sure if its a setting I got wrong, or maybe just subpar filament (unknown brand). The dark areas directly match with where there are layers that have black in it.
