I don't see that this requires any edits at all, really. There are no technical deficiencies with the photograph. Everything that needs to be in focus is in focus. The composition does a good job of conveying the scale of the tree against the cat, and provides context for the nap in question. It avoids being another subject-spang-in-the-middle photo.

So, what are you trying to accomplish with the final result? If it is to imitate the hyperartificial punchy look of the magazine photographs you see, wind up the contrast and saturation a bunch, and either use your channel mixer or lasso mask tools or what have to you to bring down the brightness of the sky in the background to make it bluer. If you really wanted to chase trends, the internet seems to think you should have used an ND filter and taken this at ƒ/0.8 or whatever to ensure that all objects more than one molecule behind the cat wound up wildly out of focus with exaggerated bokeh.

But personally I wouldn't bother. The world is already full of punters cranking out fake images. Why go through the trouble to make a genuine image look more fake?

If needs must, here's what I did with it:

This was:

• Brightness -5
• Contrast +10
• Global Saturation +10
• Cyan Pseudochannel Lightness -15
• Cyan Pseudochannel Saturation +5

That's all. (Using Corel, not Darktable. Big hammer, world full of nails, you know how it is.)
