Some shots of Old Montreal - With my new Fisheye

Just got a fisheye lens that I tried out earlier today. Truth is I have no clue what I'm doing. Anyway here are some shots:

Any advice is always welcome!!!

Nice first shots, I really like the old silo photo one of my favourite things to shoot when I am in Montreal.

Thanks!

These are fun Bucky! One thing to watch out for is using a polarizer on a wide to ultrawide...It creates non-uniform results in the sky.
I favour shot 5 here!

Nice shots all. I like the POV on the last one.
