Hi Mal,
Good to see you back here again! Welcome home.
On the topic of useful critique not received on Instagram, I hope the following observation will be helpful ...
Your colour shots exhibit a lot of lateral CA (Chromatic Aberration) from the 18-300mm lens.
I note you are processing in LR 6.8, which should be able to fix most, if not all of it, simply by 'checking' the appropriate box. While you're there, also check the Lens Profile Corrections too (that will fix any vignetting and geometric distortions).
I'm not skilled enough in LR yet to advise exactly how to turn these options on so that they remain on for future images opened, perhaps a LR user can help us both? (since I'm about to start using LR myself)
The above advice was written assuming you are shooting RAW, but if you're shooting jpg, it can still be done.
Obviously CA is not visible in the B&W images, but I bet it is softening them.
Cheers, Dave
