It's really gorgeous, amazing scape, I love the use of a. reineckii in the back, it adds a lot of color.
It'd look better with a white posterboard background though. I really love the various greens, xmas moss was a GREAT choice on the branches.
I only see a little bit of riccia though, correct? It looks really well pruned too. If you get rid of it, it might show a little more of the tank but I like it like it is also.
Riccia can be a pain though so I sympathize. I love the scape!
