GREAT, needs 3 finishing touches
This is a really nice render, particularly since it's almost entirely procedural! At the moment, it actually looks like something out of Pixar's 'A Bug's Life', but I believe it needs just a little work to look photorealistic.
Here are my primary critiques:
(a) The bamboo needs one more texture; there should be a sort of general, homogeneous graininess as the base color instead of pure green.
(b) That light is too bright and white, I think. Make it a softer, perhaps a touch of yellow in the color, or use an area light? The bamboo sort of looks like there's a search-light on it.
(c) I know I've said this to you before. Sorry for beating the dead horse, but please BEVEL. The joint between segments is too sharp, it should be rounded a little.
Now, I LOVE what textures you do have on the bamboo, making it look weather-beaten and so forth! And the leaves on the ground are an excellent touch: they don't need to be absolutely perfect because they are the background, but they're high enough quality that lend ambiance. And many other details are exactly right (the random tilt of the bamboo shoots, the random segment lengths, random widths, ...) :-D
Overall, I'd call this experiment a success!
