You're very good at photos of sunlight passing through clouds or trees, Robin - there are some excellent examples in your gallery. However, the very quality of your other shots tends to make me view this one quite harshly, I'm afraid.

Whilst the crepuscular rays penetrate quite well on the right-hand side, giving definition to the vertical trunks, the left-hand side of the image is quite dark and lacking in detail. Another difficulty, for me, is the road that intrudes on the lower-right of the image - not quite in keeping with the natural theme, and the fairly sharp diagonal line is a distraction from the neat verticals elsewhere in the image.

Given the limited amount of colour in this image, I do wonder whether it might have more impact in black and white. That might also allow you to experiment with bringing the texture out in the tree trunks, and would reduce the disconnect between the tarmac road and the mossy ground. A shadow/highlight adjustment in Photoshop might also relieve some of the darkness on the left.

Overall I don't think that this is a bad shot, per se - it's just not quite up to your usual standard. I'd love to see it become something more.
