@Wiggz: I did actually, yes. Beyond that (I'm pretty sure it was around f/4 or so), it began looking mushy, rather than like grass. Also, The 3rd last one was my first attempt at motion-blur, so I think I got a bit excited, haha. And as for the flowers, I was actually going for the sort of deathly, dull-ish sort of feel. In colour it was also nice though...
@desertdave: Thanks! Anything I could improve on the others?
