Fit looks good Zissou, but the sleeves are definitely too short. Similar to you, I always say it should be between the bone in your wrist and the first knuckle with blazers. Even second knuckle is fine and probably better with outerwear. I had to shorten a blazer/coat (outdoor) recently and I was really worried about it. It had a snap clasp that had to removed and re-sewn on too. Fortunately the tailor did it perfectly and gave me half off. As for the body length, it looks fine in the front. I suspect it is a bit short though. Without being too forward, I think we'd need to see an arse shot.
