Neither Skibbz's or yours are any better than each other.
Yours is simpler and plainer in terms of colour and depth.
Skibbz's is more stylized and honestly is a better recreation of the source material. (In terms of sheer likeness with the posing and the framing and various other features. And yes, I am aware that the nobility in your version has blue hair and a crown.)
However both are equally sub par. There's no improvement here. Anything you have done has been counteracted by the lack of similarity to the source and the bland lighting/noisy DoF/i could list problems for a while.
There's no shame in editing. Infact, without editing, skibbz's wallpaper would likely have looked worse.
My point is, Don't go hating on what people choose to do. Your 'improvement' is barely an improvement, (In my opinion, of course.) and you should just accept that some people prefer edited images. It's fine to dislike what Skibbz does. But when you try to re-do his work to prove a point it doesn't really shine on you well.
6 out of 10 work on your mood lighting and depth of field kthx.
