Wow, nice fluorescent image. :) The focus here is slightly in front of your subject. For such macro shots, you should be using spot focus and a little tripod or beanbag, but I'm guessing at 1/6s, you were using something already. Manual focus would be even better if you are good at it (but my eye tends to focus worse than auto-focus, so I never use manual). The other focus trick for macro work is to set the focus roughly, and then move the camera forward and backward. You could also easily get away with closing the aperture a little to widen the depth of field. For editing with an image like this on DPC, I would tend to mute the saturation a little, so it's not quite so over the top, and maybe shift the colour balance a little away from the greens.
