As promised herewith the new pics.. I tried to create a more sloping effect by increasing hight on both sides of the aquarium.. (it's being held back by black slate) this black slate will be not visible after planting.. What do you think dutchy..(more hight?)
I think the height is ok but the big stone on the left attracks more attention than the path to the back in the middle. Do you have a little bit smaller one? You can push the slate a little bit more downward until it's almost not visible.
