Mosaic commission work in progress

This is the start of a half scale painting design for a stained glass mosaic I am designing for Abington Town Hall- for the town's 300th anniversary..the arts council will actually do the mosaicing under my guidance.
It will hang over the main door on the inside of the building.
There are three panels, this one is the middle one (hard to get a good photo) the finished panels are approx 12"x68"( middle ) and two panels 12"x31" on either side.
I will depict the Island grove in this one ( see photos below) and the other two on either side will have a beaver( town mascot) hydrangeas, strawberries and shoes. Not quite sure how this is going to go but it's a fun challenge!
