First of all, thanks for everyone's thoughts and comments, I really appreciate it.
Couple of notes now that I've had to read and understand everything (sorry if I've missed anyone out).
1. I think I miscommunicated a little and we've come from different directions as Tom points out - the idea was to show some photos that come from a kind of restorative solitude, not to illustrate solitude itself. As an additional note into how I was thinking, these were both taken after long days/ periods of time where I was constantly surrounded by people/talking - it's really draining to me, and photography is a way of restoring balance.
2. Thanks everyone for the edits - each of them has helped me get a perspective on why I like this photo as a starting point. I've rethought and reedited and come up with something I like better thanks to everyone:
Main points I've taken:
I increased the contrast between light and dark - trying to take a bit of emphasis off the ceiling and more on the lighter parts of the scene. (Thanks Robert and Maggie!)
I softened the hotspot - I'm not comfortable with cloning it or the lights out, but I think this helps it not be as distracting (Thank you John).
Perspective correction - I think the vertical poles are important to how I want to fit it together - and as a bonus I remove some of the top left as John suggested.
Finally - thanks to Asher's b+w, and Mark's comment, it became obvious to me that, yes, the colour is actually important, so I've tried to emphasise the difference between the ambient and the artificial lighting.
It's still a work in progress and I'm going to be leaving it alone for a few days so I can come back with a fresh eye.
3. My poor flamingoes
Honestly, my brain reads them as similar images (as in, I feel an instinctive need to group them together). Everyone's points are noted though - I guess it's a case where it feels right to me because I was there, not because the image works as well as I'd hoped.
Thanks everyone for contributing, I've been having lots of fun!
