Flooded quarry, Swithland Woods

The Charnwood Forest area of Leicestershire is very very ancient rock and the woods in this part are pitted with these old slate quarries - very deep and quite dangerous.
I've meant to draw here for a long time and thought it would make a nice change from the canals and river in my waterways project with it's woods and steep hillside - the rocky side is hidden in shadow. I may try to get there at a different time of day when it's lit up. I also plan to visit other flooded quarries, bigger and deeper - though I do like this little one.
I've mislaid my little battery operated eraser, which would have been perfect to draw those light branches back in through charcoal - so I had to carefully(ish) leave them unshaded.
I think this might make it onto canvas as I like the composition - what do you think?

I think of the Hobbit too - Old Man Willow may be lurking somewhere there :>) I have actually got a fantastic - though sadly poorly focussed - image of a green man in the bark of a tree not far away, complete with horns, high cheekbones and a goatee beard.
I just hope nothing with giant arms and tentacles reaches out for me like it did from the lake for Bilbo as they went into ?Moria :>O
thanks :>)
I like the cards you've designed for Etsy :>)
