So here's a bonus of my Raise Your SHIELD Wallpaper Pack, guys. I added a tile flooring to add to the 3D effect, and removed the text to make it more simple. Honestly, I love it and I'm using it until I create/find something better. Enjoy!
By the way, for smaller screens, if you set it as your wallpaper, use the "fill" setting so you get the whole image on your screen. Using "center" will only give you a portion of it on your screen and take away from the 3D perspective effect.
