Progress on unfinished painting based on stained glass windows.

I have been working on a new painting which is based on stained glass windows.   I wanted the artwork to have the translucency of a stained glass window.  I began by looking a nebulas, black holes and space photographs so I could get an ethereal look to the painting.  I have kept a limited palette of colours as I will be overlapping the oil paint so the colours on top will change the under painting.
