Hey Jill, keep in mind scaping and layouts are completely personal preference, so do what YOU like!
To me, the hardscape is too symmetrical and mismatched. Plus once you start to grow things it will be quickly covered.
I do like the two dark driftwood pieces, but I feel they are a number or two too small for your tank. If they were all I had, I would combine both of them off center. If you cut your tank into three virtual slices, I would arrange the two pieces at one of the "cuts", if that makes sense?
While the other branchy wood looks nice, it doesn't go very well with the more typical driftwood. Perhaps if you have a smaller tank you could make it the "centerpiece" (off-center :wink

there. The rock... maybe for throwing?
Again, just very personal observations, and you need to find out what is pleasing to your eyes. What happened to your 65gal tank?
