An interesting image that meets the challenge well
I find your stated mood interesting for the shot and one or two of your commenters came near to guessing it right but for me the sun and its glow is such a dominant aspect and I normally associate it with happiness and good things the mood it conveys to me is 'anticipation', the twig will be producing buds and growth will be coming soon. This is quite a difficult challenge to convey the mood you want effectively through an ordinary mundane subject. I think if you would have given much more emphasis to the web then yes, that would much more effectively convey a mood of 'apprehension'
