This is very nicely done. I really love the colors in this one, and the water droplet looks very crisp and sharp - and you managed to get the water droplets without any "work reflections" (reflections of cameras, spotlights, etc.). The DOF isn't very deep, but it's obvious that that was intentional, and it is focused in just the right place.
I also love the composition; the square crop works very well in this shot, as does the berry cluster being slightly above center. You captured the color very well, also - it has a distinctly autumnal look, which seems appropriate since this was taken back in October.
I do have one problem with the technique, however. If you've read any of my other critiques in the past, you already know where I'm heading. Choosing the correct ISO can make a big difference in the contrast and grain of the photograph. I'm not saying this is grainy, but you could have lowered your shutter speed a little and gotten away with using ISO 80, 64, or even 50, and the grain would have been very near invisible. Like I said, this isn't terribly grainy, but if you look at the lower left corner, you'll see what I mean. I think you'd be amazed at the difference a proper ISO would make. ISO 400 is far too fast; for a shot like this, you should be using an ISO of 100 or less.
