The rock on the right is upside down. Do it about 5 more times.
well I like it and if you like it and its stabile then that's all that matters
Looks pretty good to me; what is her objection? I don't particularly like symmetry, so if it were my tank I'd not have the two high points at the same level and I'd not have each the same distance from the front glass - but that's just me! Very nice rock BTW.
I would suggest 2 islands. one can be the largest rock, the other a smaller pile of 2 or 3 rocks. and if you have to, one very small third island in front of and separating the other 2, but offset adn not symmetrical. Asymmetrical is more appealing to our eyes with non-symmetrical items, as is the rule of thirds. odd numbers are also more appealing to our eyes.
