I know the crypts. on the left side haven't fully grown in yet, but even when grown in I think it still may leave that space too open. The rest of the tank is FULL of plants, and has a very nice gradient from background to foreground. But on the left side you see the Blyxa Japonica and there's a sharp break between it and the Crypt. that breaks the flow of the scape. Also, this may change once the Crypt. fill in completely, but the fact that you can see the back wall really takes away from the stream effect. I feel like I should be looking out from a canoe in the midst of the jungle seeing all the lush dense growth coming at me, but the back left just breaks that feel. Kinda like a clearing or something killing the mood. Maybe some B. Aubertii

behind the B. Japonica to transition to the Crypts. ?
The plants look AMAZING and whatever direction this scape goes it is a great idea to have a long lasting scape rather than a short lived one. Overall this is an amazing composition ( I can't believe you can get the L. Acurata that RED) , but these were the things that kind of distracted my eye when viewing the photos.
Thanks,
