"Sailing Center" side-by-side 16 x 12 oil

"Sailing Center" finished                                  "Sailing Center" not quite finished

Yesterday I posted my painting of the Cohasset Sailing Center from our North Meets South Paint Out.  As with most of my paintings, I place them in my studio where I can look at them in passing to see where I may need to make adjustments.   I thought a side by side comparison of the painting I brought back from on site, and the finished painting would be useful. See the finished painting on its own below.
My process is that I do NOT use a photograph to finish the painting.  All the information I need is in already on the canvas, and in my head.  I review each edge and each plane, looking for inconsistencies, any unintentional geometry, confusion, notes that don't ring true, color temperature and freshness. 
Above, the finished painting is on the left.  I looked at every upturned plane to make sure it was cooler than all down-turned planes.  I added the harbor through the windows.  When we left the painting site, I had included some notes about the value through the windows for reference.  I refined, slightly, the large brackets beneath the roof.  I vibrated cool into some of the sky-facing planes, added some interest and warmth to the inside of the building.  I softened some edges, cleaned up some small perspective issues, and even moved my signature. 
What do you think?  Thanks for looking!
