Tree of life stained glass panel

I am making a "tree of life" stained glass panel to fit in a long, narrow window that is high up on a wall (10' ceilings) in a Victorian era shot-gun house in Kentucky.  The window has restricted back light because of thick pine tree branches that cover the view.

 This is a close up of the panel. I am using Uroborus bright, grenadine red on clear wispy glass for the fall side of the tree and a bright yellow agate slice with crystals for the sun. The background is Spectrum clear crinkled glass. The texture of the background glass diffuses the light in different directions.

On the summer side of the tree I am using Kokomo dark green and lime green on clear wispy glass for the leaves. The middle of the tree, where the leaves change from green to red, is cut from Kokomo green, cerise, ruby red on clear streaky. The trunk and branches are cut from an opalescent Uroborus glass, and the bottom of the window is cut from Youghiogheny beige, copper, cobalt blue with a dark green stipple. It looks gorgeous with a minimum of light behind it. The window will be copper foiled and encased in 1/2" wide zinc came. To aid in structural support I will add curved, narrow re-bar along the top of the ground line as well as copper re-stripping in strategic areas of the tree. None of the structural support will show.
