I've probably posted about this before, but oh well.... The question an artist faces of 'knowing when to stop' is a common one. As a young artist I always felt that in time it would become easier, and that as I matured as an artist I would always know the the right time to set a painting aside. But in truth, I have found it's a question and a problem that never goes away and always remains.
With this painting the urge to put in one more brush stroke, to add one more flower, or to remove/ rework a section of flower bed has been (it seems unending). Even now (though finished) the urge is strong, and I know in myself the painting had all the elements in place sometime ago, and yet I've continued to tweak and continued to play. It's been fun, but the actual improvement within each revision has been perhaps minimal.

I think however, the biggest difference in 'knowing when to stop', is that as you become more experienced, gradually over time you get better at hiding the 'extra fiddling'. This painting (I hope) continues to look fresh and strong, and the reworked elements are hidden sufficiently to allow the painting to continue to look fresh and alive. So here perhaps is a saving grace of a few more years under the belt.

As an aside I really enjoyed tackling this subject, drawn by the beauty and complexity of the garden and the wonderful architecture the mission church provided. These buildings of age and beauty sometimes seem to far a field on the west coast of America, it was fun to put one too paint!
