Dusk at Denver Botanic Gardens

Effective composition? What do you like? What would you have done differently?

Any and all reactions welcome.

I think I would add the corner of the pond enclosure, but also worry that would add too much of the concrete walkway.  There is one spot in the water on the left that may be sensor dust.  I'd consider eliminating the reflection of the white flower -- it's real, but it's also distracting and not in accord with the harmony in the rest of the sepia tones.
