5 - Like it. Criticism; wish it were 640, in this case height. Colors are nice, dependending what is there, more inclusion of context (especially of whatever that maroon colored object is) and possibly even more width, may have made this even better in my opinion. Difficult, but also a little sharper on the in focus blades of grass would also have been good.
Very nice narrow DOF but there's no subject really -- you create a focal point with the focus, which is better than none at all, but still, this would be a far better image if there were something of interest as the focal point rather than being a photo of whichever grass blades wound up in the area of focus. (I say this with kindness and appreciation because I totally take this kind of picture all the time.)
