Great jacket, I love it!
I love just about everything about this jacket- the style, the leather, the quality, the collar, the shade of brown, etc etc. My only two 'improvements' would be to do away with the sleeve buttons and just taper the sleeves a little more instead. The second would be to make the lining warmer. Maybe use thinuslate?
Anyway, it's a beautiful jacket. I will wear it as often as possible.
