Look like a solid start to me! That scape is a very common type of "everybody's been there" i believe. But i have not seen anybody that can keep up with it till it matured. For a few reasons, plants fill in and "the river" is being forgotten. Eventually it gets faded from the scape and then the tank gets re-scaped. That's what happened to me and i've seen an other couple of people had been through the same process. Anyway, i would suggest moving the small branches along the river. Have a low carpet at the front and around the river. What i'm trying to say is to keep the river as your focal point and everything around is supposed for popping it out. I understand that, once a dirt tank is set up, its very hard to move the substrate around. So a solid plan at the beginning is needed. All in all, what ever i've said above is just from my own experience and my own view. Hope it will give you some idea. And please don't complain about the 75's depth as i'm stuck with a 55 right now till the end of august so a 75's depth is now my every night dream lol .
