What a pleasure to review and critique your image ... Third challenge and top 20 already.
First Impression - the most important one: This is so cool .. I loved it when I voted on it and looking at it closer .. yup still like this one.
Composition:
I like the way that this is framed ... For my tastes it is a little working on the centred .. but this may not be able to be helped.
Subject: It definately meets the challenge ... I think it is acutally quite a clever find something like this in nature.
Technical (Colour and light):
I might have worked the contrast a little more to see what else could be brought out. I like the natural light of course ... but taking the shot at different times may also give different perspectives.
To grow its vote?: You did so well .. congrats .. I am not sure about how to grow this one .. but continue playing and learning.
Summary: Fantastic find and great shot!

This is a superb tree.......Munch would be amazed.....even the flowing sinusoidal curves look like his painting. I wonder when you first spotted it....long ago, or just before the challenge?
