Wonderful colours and lighting we have here - I really have the right 'sitting in a greenhouse flooded with light'-feeling, now. The greens of the plants are so vivid, the colourful background underlines the happy message in this. There are a few things to change for a better though. First I think the display size is way too huge. I cannot fullview this without ctrl+- on my screen, and I doubt many others could. I recommend a display size up to 1000 Pixel on dA. The simple, but effective shapes in your photograph allow an even smaller size. The framing is not my thing either, but that's often a question of taste. A bright and mellow photograph like this does not need a stringend frame, it can stand out all by itself. I really like the composition of this with the relatively large negative space on the upper left. There is a dark thing in the upper right though, with which I can't quite agree, because it looks unnatural and disturbes the otherwise peaceful scenery.
Of course I read your description and it's really brave to state the flaws. I wrote a critique to help you enhance the photograph in my point of view, how else should I be able to state a critique? I cannot know and compromise all those oppinions out there - you might even find someone who hates the picture to death and another one that says it is the most perfect picture to make of this scene. Critiques are never valid universally, but have always the oppinion of the writer in it.
I don't doubt, that you've done your best, chose the best angle and cropped it like you thought it was best. I don't know the place and I'm sure you have done the best to depict how you read the scenery.
About the colour, green. I saw the title and then the picture and what I saw was not matching, another deviant wrote "autumn" in a comment instantly, because that is how the colour is making the viewer feel the picture. Golden, yellow, brown and orange hues do not say: 'it's spring' - it is not about liking a colour, but how it transports a message.
