Based on a Eucalyptus Stand next to a lagoon.
I actually found the most productive setup for working today that I've found yet. The Live Oak Library, in Capitola, CA has excellent Wifi, and my Solar System on my Mobile Art Studio is working perfectly -- so I was able to livestream all day at the library while sitting and staring directly out at the trees I was painting.
Reference here:
I ended up using this painting a few times, just different parts of it. I would basically take a part of the painting and use it as a backdrop for a scene, and let the scene play out over a couple of pages, focusing on different parts.
Had to repaint light on some characters, and do some little modifications, but it improved the overall quality of the panels / pages by a significant amount.
The little flower looking things actually look like little eucalyptus, which then turns into the oily long leaves.
It's strange I guess, because there is another breed called Silver Dollar Eucalyptus whose mature leaves have the same color as the smaller leaves, but are mature and smaller in shape than the long dark green leaves of the mature trees here.

Also, I wanted to say thanks to 
I'm actually not that up to date on what @Neoxian Community is all about, so if you'd like to give me some information, I'd appreciate it.
I'm going to go ahead and list the last three entries here:
