Is that anubias behind the lobelia? How did you manage to do that because thats a sweet look.
I think your biggest killer is going to be the symmetry between the monte carlo, lobelia and foreground plant on the right, hygro? Even though the monte carlo is a u. its basically the same size and direction of the two foreground plants on the right. Also is that a small lily infront of the rotala colorata? I think it blends in too much with the bottom portions of the colorata and does not add anything.
Either way good on you for getting at least something presentable. Unlike me this year.
