Definitely a tranquil image. You are most fortunate to have a place like this as your lunch setting. A bit of editing that I would suggest would be to tone down the brightness of the lighthouse and increase the brightness of the rest of the shot.
This would make a good shot even better.
Yes, it must be a great place to sit down and relax. Anyway, it's a good shot, but I do agree with Trisbert. Thank you for sharing a nice spot like this.
