I really like this. There are so many different shades and so much texture. The splash of green in the lower right (your plant?) really adds a lot. Best of the raindrops-hitting-water shots in the challenge.
I like the patterns in the dark sections and how they are diagonal. They probably aren't interesting enough to garner a high vote so this will end up with a mid to low score. A tighter crop, cutting out the lower left quadrant, might have increased the impact of the photo.
