It was a long time ago, that i visited this part of the forum, and that has its advantages, as i can see this dirama grow by every pic that is in the tread.
It is going to look fantastic Phil, and i am not wondered about that, as i know how much affords and research you put in your diorama's!
Even when the fig tree is an awesome piece in this dioramma, in my eyes, the hanging tree over the river does the trick, very naturalistic Phil!
When i saw the brown water in the first pics, i thought..., ok blurry water, natural, but after you made the shiny surface it was fantastic, and very very realistic.
Really great job Phil!
This diorama is one that reminds me of the edge of a jungle, going over into the grassy swampy area's, where the Indian rhino like to go for their food and for their cooling off in the water.
Only that the last part of the landscape is more open, without too many trees.
You know from your fish-business, decorating is sometimes the art of letting things away, instead of putting more decoration, so be carefull to add too many different plant species, even when it does look good on and in the diorama.
But so far so good my friend!
My only suggestion would be, to make an area at the edge of the diorama, where the open area is, with lots of reed, going up quit high, and let an Indian rhino get out of there..., meeting some waterbuffalo's...
Maybe some little water-parts(swampy) to make it more realistic,
Just an idea.
But at last, again..., fantastic work, and your diorama will be superb!
