Initial wood set up was best (should have tried the little piese of wood where I suggested just so everyone could have a look at what I was mentioning
).
I don't care for it much.
You have a big "circle" of wood in the middle. The bottom looks like a couple of crab claws coming tights at you. Also, that one stone seems flat out centered.
I do like the continuity of the wood you have selected. All but the one piece that runs to the top left of the aquarium "match up" and make a very believeable vignette. Remove the thin bit and you completely harmonious!
Rocks look much better than the initial photo, too! Odd number always looks best, and you can see it in action right there.
I think you are almost there. Consider moving the whole hardscape over to the left a little more and work out that "circle". If it takes a few more hours/days...so be it. You have put so much time into it up to this point a little more time isn't really going to matter. It will mean the difference between the good hardscape you have now and the great one you are very close to putting together.
