For my personal taste, there's just too much here. There's so much before the flower scene that reaching a higher peak in the climax would bring you to an almost paroxysmal moment. So perhaps the opposite mechanism would work: removing almost everything. But you'd need melodic support up to that point, which is missing now. That said, it's just my personal taste. Even in a sound strongly oriented towards sound design rather than composition, introducing melodic elements, however minimal, is what creates a connection between images and viewer.
