Yeah i guess i am trying to go for that look. Ill give your idea a go at moving some big plants to the backwas your intention to make a kind of valley going in the middle? I think it looks pretty cool. And the tall plants at the front dont bother me, I think they look good, but maybe more tall dark ones at the back could provide more depth?
Yeah ive notice those Aluminum leave falling off, they were one of the first plants i purchased and didnt know much about them, thanks anyway for your inputalso, get rid of that aluminum plant (the one that is green and white), it won't do well under water
