Layers of moments

Layers of moments as I trace the shadows.

I chart their course across my window pane, my eye and hand try to keep up and record the reflections accuracy is not the main aim.
I have numbered the groups of shadows in milli second intervals. Now looking after drawing I am seeing topography and weather maps .... weather maps work. I aim to now seperate this image and print it in 7 layers with solid and patterned zones.
