It almost looks like a drawing to me but upon closer inspection I can see that it is a silhouette of the vine. It might be a little too subtle for this crowd but kudos for trying something off the beaten path.
How come you missed the brown? You got the suck brown (now visible with Rob's new code sequence) and it makes one of the great browns, i.e. a genre of its own that flies right under the radar of dpc standard ribbon but is undoubtedly a worthy picture.
Glory glory glory, wham bam minimalism and all there.
I like this image. But the fact that it looks like you could have drawn it in MS Paint will hurt your score I bet (not a bad thing, not trying to be snooty or anything). It is at least original from anything else I've seen in the challenge.
