My first preliminary drawing of the left side wall was just to get an idea of the direction the customer wanted to go in.  They liked the general look, so I proceeded with the front stage/proscenium (depicted in the next shot).  This drawing here shows curtains on the side walls towards the front of the room.  I plan to use an acoustically transparent material for the curtains and install sound absorption panels behind these curtains to tame echo caused by "early wall reflections".  There is the possibility that a landscape mural will be painted between the other columns (wrought iron area) to give the effect of looking out from a balcony.

Here is my rendering of the right side of the front stage/proscenium.  We will have heavy duty theatre curtains that will run on a motorized track behind the proscenium.  It will be automated to open/close when the theatre is turned on/off.  This image also shows the planter/urn on the flanking walls. The design of the room has now changed from the drawings and there will not any arches in the room. Instead, the builder (Doug Buchanan of DB Construction) came up with a great idea of framing in domed ceilings.  Framing shots below clarify how these changes will look.
