Based on the style, choice of medium, and detail, this seems more like an esoteric attempt, and it is very forced and somewhat stilted. Still, I like the movement within the figure, and I like the green.
Every piece of art has a meaning, and I suppose that this could be a sort of natural spirit condemning humans for the pollution/rape of nature, to the proverbial point of no return (or otherwise an environmental and naturalist essay depicting the ever-growing dialectic of man versus nature); however, I doubt the OP thought this far ahead. It seems like the esotericism stems from the artist, and not the art itself. A deeper meaning could be pushed or developed (for example, green and orange would contrast quite nicely, going back to what I said. Also, the implementation of the proverb sounds more like a saw--get it? [saw has more than one definition]), but, it would be quite futile in such an environment (which is a commentary on NG, rather than your talent).
Still, it is a quaint little piece, which still has the mystery and emotion that deserve praise.
