there's not much difference between this and the original picture, enough that Google was able to immediately find it.

The text isn't that readable either, and has poor placement/size.

The piece lacks movement.

Tbh, you'd be better off using straight renders rather than wallpapers, it encourages you to be a lot more creative.

Your font choice could be better.
