I was just going to say, the stick on the left should point the other way... Everything is pulling the eye away from the centre of the tank to the rear corner. maybe excessively so.
The thing with the driftwood on the left is it has a natural curvature, if i put it the other way the branches would point to the back. I like the look of the branches coming to the front
I got all or more than I needed of driftwood and stones to scape my 75g. It was the first thing I collected, before I started gathering my filters, co2, and lighting. I would do an arrangement, and then let it set for a few days and rearrange it again. Tank was empty for about 10 months as I would get equipment as I could afford it. I kept taking pics through the process, as certain pieces looked good a certain way, while others just didn't. I also used masking tape and marked my tank into 3rds using the Golden Rule or whatever it's called. I seriously must have rearranged 100 times before settling on the final layout. Like you said it would be 95% right with one branch just not quite in the right position! By the way where did the hanging plant rod above the tank come from? Stealing that one!
