I actually reallly like it... Those driftwood pieces are fantastic, I love them! I think I'd prefer less rocks in the centre - more open space. But I still like them being there and think they add some ncie contrast to the tank so it's not only driftwood and plants.
I also like the substrate - again it adds a little depth, some difference and contrast. But I've never really liked monochrome substrates even though I have something darker in my own tank.
I think it looks good! Can't wait to see how it goes.
