I think that the red is oversaturated in #2 and #3. Easy enough to reduce in post and seems to be a characteristic of some image sensors. Reminds me that I have to do a couple of edits on my website red flower images!
Otherwise I liked the way you treated the images.
Keep at it! BTW - most women have a better perception of reds than us guys!
There is a caveat here - images for the web should be converted to sRGB before posting and the OP's monitor has to be able to display the Adobe RGB pallet in order for his workflow to include that gamut. I am using a Spider X (recent version of the Spyder hardware) and, depending on the monitor I am calibrating use either the SpyderX Pro software or DisplayCal (which is free but needs a colorimeter).
Printer and paper calibration is another story, but I find it reassuring to know that whichever display on whichever device i am using shows closely-related colour tones. (2 laptops, 2 4k screens and a desktop with an appropriate video card).

No idea why it shows 24 hours... Don't forget that it will only show apparent time - as the article says, being offset from the Greenwich meridian there will be a time difference between standard and apparent time. And the beach is wonderful! I was brought up not far from there.
Great lighting and sweet subject!
I read recently of a curved (I assume that the curve is parabolic) image sensor which is being/has been developed. Pixel-shifting such a sensor might give you the results you are looking for... Very interesting project you are working on and I personally like the results you are getting. Good luck in getting the results you are after nd have a great 4th of July.
Oops - the OP was talking about tablets - sorry I went off topic!
I regularly calibrate my laptop screens and 4k monitors with a colorimeter and get consistent results, so yes, you can calibrate a laptop.
It is frustrating when an external monitor connected to a laptop does not give the same results as the laptop - especially if you have spent time optimizing the photo in post-processing. Putting your photos on a USB stick and taking it to a friend's or to a photo club for projection and ending up with bad colour is embarrassing, and taking them to a printer can be even worse! As stated elsewhere, the larger the resolution and size of your monitor, the easier it is to get the results you want in editing, but the key to faithful colour reproduction is calibration.
Windows 8 and 10 have reasonable calibration software built-in, but you can get better results by investing in a colorimeter and learning how to use it properly.
If you use a separate screen with a laptop, I would also recommend that you use the "extend display" option and calibrate the external screen. The effort is worth the time.
I have been reading UHH Digest for some time and found the content interesting and diversified, so now decided to jump in with both feet!
Started making contact prints from 4x5 negs found in my grandmother's attic in the 60s and went as far as a Mamaya C330 in late 60s before dwindling to 35mm in the mid 70s. Did lots of B&W processing and printing but never got to colour processing at home.
Got into digital early on doing a lot of photos of fine art (you really learn a lot doing that in natural light!) and found Nikon's ergonomics better for me than Canon's SLRs. After a wrist injury, started using a D5500 although I kept my D90. I still work occasionally with a 645 and 3 lenses, but not doing my own processing, so I find the cost high using others to process and digitize.
Covid self-isolation has me going through 12 years of digital images and honing my post-processing skills. Mostly using Capture NX and ON1, but have CS6 suite and CC photographer's subscription. I find PS sometimes does better building panos than ON1, but ON1 suits my workflow better at the moment. Maybe the recent upgrades across the Adobe product will change my preferences, who knows?
Now pondering mirrorless, but in a holding pattern due to the cost factors.
Well, that was a lot for an intro - hope to share some shots (images, photographs, pictures, pixels?) with you soon!
