Hello everybody! I don't do many panorama shots but I've had a go at a sunrise at the beach this fine morning. My goal here is to get a big canvas print out and give to my dear mother for her birthday! So I'd like some critical eyes

basically any flaws in the picture or any suggestions to improve it would be very much appreciated

It's compressed for upload purposes so don't mind that, I have the original format to take for printing.
Thank you!
