Hi Petrus - I really like the colour version, the greens while garish, are also probably about right. I know this because where I now live, the summer starts a little later than the rest of the country and so the vegetation when it does get going, seems to be on steroids or something and produce those vivid tones. So yes they do look a bit over the top, but I also think that in reality they are probably quite near to the same colour as seen in your image.
Compositionally, I like the sweep of the image from left to right and also the weight of the shadow in the foreground. You have managed to get good tones and light balance through out the image, as I can see detail in both dark and light areas, which is not an easy thing to do in those lighting conditions.
But alas I also have to agree with fike, that the fuzziness in the ferns is very distracting and I actually find them quite difficult to look at, which is a real shame as due to their brightness and location within the image, makes them one of the main focal points.
My tip for next time you go into the woods, is either wait for a similar day but with very little wind, or alternatively keep the same DoF, but increase your ISO and shutter speed (1/250 should just about do it if you can) and overlap the shots by at least a third or possibly a half, that way when you do get movement between frames, the large overlap should hopefully give you enough wiggle room to eliminate any obvious movement when you stitch them together.
