Is it worth to learn the post production of photos?

Hi everyone,
after a lot of time, I'm trying to do microstock in more serious/professional approach. Until now, I have uploaded some photos of my travels with no post-production effects.

As you can verify, in general my photos are good in composition but they are certainly boring, a way to improve the quality is the post production work.

My doubt is if is it a good idea: is not better to upload the photos "as-is", as the buyer can buy the photos and modifies by himself (or by some professional) as he want?
If I sell a photo that I modify in post-production, do I have not the risk that some potential buyer can skip my photo because it's not as he want and, in the same time, he can like to buy the not-modified version of my photo?

How to manage the post-production work to match the wish of the potential buyers?

Thank a lot for every feedback

hi there in order to make your photos to look natural, cause in the end its what the buyer wants. then go to a photo program after you fist shoot with the raw format,and just play with
highlights
shadows
whites
blacks
and change or the play with the white balance
stay away
from filters
from tooks like
vibrant
from saturation. or ad 1 or 5 percent only
and other tools
the best out there is lightroom
in microstock world they only want clean colorful bright pictures that not look fake
in the artistic world PEOPLE WANTS THE FAKE
oh and also always ad some noise reduction in your pics, cause even if you shot the pics with iso 100 then in the post proccessing pics are gonna get some noise cause of the digital proccessing
