I agree with you Jim, smiling all the time would not suit you, it would look stupid. Not saying your smile looks stupid
you have a very charming natural smile. But your serious face is part of your artistic look. Makes you come across as "sensitive artist with depth suddenly releasing a butterfly in the sky when he smiles". (your smile reminds me of the fugacious moment when a butterfly leaves a flower to fly away) Shining like the sun all the time would destroy the effect. I think you're much more impressive when your face is grave, and your smile a hidden gift for those who touch you
