It's not bad...not bad at all. The main thing you need to work is simply avoiding symmetry - clumps of plants the same size/shape, and regular, linear arrangents of the plants. I think making it "live" would be as simple as skewing the arrangement of those three bacopa(?) in the middle, maybe trimming them to different heights, and waiting a bit for things to grow in. Don't get discouraged!
Knowing others, one is wise; knowing the self, one is enlightened. In conquering others, one is forceful; in conquering oneself, one is mighty.
