Great details in the dandelion! I love what you've done with the toning down of the color saturation. My only complaint here is that there's not much detail in the bug - it blends right in with the background.
A touch oversharpened -was it NIed as well?- (you've probably already been told though). Comp is nice and vg dof (nice bokeh you have going on too). Dead center comp is risky but I think it works here.
Second pass: effect (sharpening/smoothing) fluffies works, image as a whole works with song (good choice of songs!) - bumping up. Good luck.
I think this is a beautiful photo, but it doesn't say "yesterday" to me. I'd give it a 9 for the look of it, but am going to give it a 7 because it doesn't really "bring the title to life" for me.....I suspect you took the image and then tried to find a lyric to fit it!
