I like the soft water color quality of this render, but I think it might be a little too low in contrast. I'm going to bring it into AfterEffects and see if there's an color correct. That will save me fumbling around with lighting and endless rendering settings. Haven't tested ambiant occlussion, that might be helpful, but I'm not sure I'll have time for that. I might add flowers to some sections, but will leave it for now.
