This works for me very well. I love that we know what it is, but also that it's abstract. Also, it's subtle, but the work is divided in to three main vertical sections and I like that too. Maybe it's a tad dark on the far right bottom half, but that's an easy fix if it were something you also thought needed the adjustment.
Went with high-key treatment this week to create a somewhat abstract image of the bull rushes on the edge of the lake close to our house (coincidentally called Green Lake). The early morning sun created a wide range of greens.
