I agree with all who have posted so far and also suggest a rock or three (odd numbers seem more natural) I like the looks of rocks at the base of larger plants...as though they are sprouting out of a pile of them, it seems to soften the line from the plant to the substrate.
Overall I think it looks great. Some more color and maybe a larger leaf shape would be all I could think to add beyond a bit more hardscape.
