Hi Iain,
sorry about the unexplained fish losses mate, hopefully there finished now and ill look forward to the new additions.
Really pleased your winning the algae battle with your hard work and persistence
The pipework you made is really unintrusive and you must be well pleased with that
As for it looking flat on the FTS, i think it looks awesome, but i can see why your being a little critical. I think this would be negated if you trimmed the central rear stems into a dome shape above the ferns. This would give an island shape, but i do love the look and the layers of plants you have created. The ferns and crypts have filled in really naturally and the fissidens and mosses are looking great on the wood. As the bba in the foreground is reducing the tenellus are really filling in and thats looking good too. The first photo really gives a sense of the depth of this tank and you have done really well to battle the issues you have faced.
Noticing more little touches i like about this now such as the rock in the left foreground which is being softened by the carpet and the illusion of depth (not that it needs it) created by the different sized left and right branches reaching to the substrate.
Ill take inspiration and knowledge from this island scape which will stand me in good stead if i ever plan one myself

.
Great tank.
Cheerio,
Ady.
