Right, time for some opinion-seeking...
I removed the plant pot, & knocked the bloomin' bogwood over while I was in there. It's not the first time, so I ended up recruiting the bogwood from the far right of the tank (with the peacock moss on), & now the tank looks like this:
I like it, but still think it's lacking something. I tend to do this kind of planning better visually, so I started making up a picture-plan:
...Went off to boil the kettle, & when I looked at it again, that purple patch really stuck out. I had been attempting to make the bolbitis the focal point of the scene, but am now wondering if that wee well in the scape wouldn't make a better one? Now that I see it highlighted like that, I really like how the surrounding bits seem to flow into it, & think it needs something to draw the eye. Perhaps, instead of filling the gap with a wee plant, I could try some pale wee pebbles, or just pristine sand?
Here's a closer look at it... What d'ye all reckon? (you'll have to pretend that dodgy bit of moss-covered filter sponge on the substrate isn't there, heheh.. I'll be removing that & stripping it down to plug some gaps elsewhere.
