Hmm. I think you could make this better if you increased the colors and light a bit, at the moment it feels a bit flat, dark and dull (you say spring sun is shining, but it doesn't really feel like it). Also I'm not sure what I think of the composition. I like that there's 1/3 green and 2/3 blue, but with the grass in the foreground like that the bottom part draws to itself a bit too much of my attention. The crookedness is interesting though, but I'm entirely not sure how much it works. Just my two cents.
