These are processed from the camera RAW file, an approach I always take when I am aiming to optimise my camera's output and take the full advantage of what the DSLR system offers me. I will only use camera JPEGs when I am taking a lot of the same sort of shots in very consistent conditions (eg lighting and dynamic range), and where I am not needing to obtain the optimum output quality (eg taking a load of shots of the kids birthday cake and the table, where the photos will only ever end up on Facebook or WhatsApp).
The processing of those coastal shots (which are in Dorset, UK) took me about 10 mins for each one. I carried out basic RAW conversion (levels type adjustments, contrast, basic sharpening) plus I like my skies and seas blue, so I would have boosted the vibrancy of the blues, then straightening and cropping. In Photoshop I used layers to apply a selective noise reduction on the sky and sea (I like smooth textures in these areas), final sharpening and then export to JPEG. About 10 mins for each.
This RAW processing approach I see as integral to the whole point of choosing a DSLR system, over for example a bridge-type camera. The way to release the full potential of what the system offers (camera plus lenses & accessories) is to optimise the output with RAW processing.

Originally posted by billdotjr I mean looking at my Nikon photos I mentioned, these were "quite fine" straight from the camera and they only needed little improvements to get to "really nice".
But, you didn't say what the lenses were being used on the Nikon camera, and also you haven't said what sort of subjects were being photographed and in what conditions. As has been pointed out here you are making considerable challenges for your Pentax camera by using sub-par glass, shooting technically in a fairly inexperienced way, shooting in challenging mountainous conditions with atmospheric haze to contend with, and not making any particular optimisations to the recorded output, neither through camera JPEG custom image controls nor RAW processing.
We don't know how that Nikon camera was set up, but it may have had the custom controls for JPEGs tweaked favourably ...., however the lenses used and the lighting / subject conditions are going to have had the most impact, and frankly created an uneven playing field for your comparisons.

Originally posted by billdotjr I just want to set my expectations right, not to chase unicorns.
Your expectations are unrealistic if you are unwilling to invest yourself fully into a DSLR system .... that means learning and experience, acquiring the right lenses and accessories that match your expectations, and taking the time to optimise the image at both the capture stage (using the camera and lens) and the processing stage (using a computer, or alternatively optimising the JPEG custom settings on the camera). If you are unwilling to invest in these ways, then a simpler camera type, such as a bridge style, may be better for you. You will certainly be able to take great looking photos with it (given certain conditions), but ultimately your potential, both in image quality and versatility, will be far more restricted.
