I wouldn't mind having my lunch there. Dramatic sky that contrasts nicely with the calm water. The trees look a bit dark, but that might be due to my laptop screen.
I am not sure I am going to use the exact right words here, sorry in advance. I like the drama in the clouds, and I am enjoying the overall composition you chose - it's very serene, but the clouds almost seem oversharpened or structure setting was too high maybe? They just feel a little unrealistic.
Wow, what a crazy sky! I like composition of this a lot. I think I like that black and white too...all tones and no distractions. A little over-sharp for my taste range, but doesn't really take away from the image.
Initial Reaction: Wow! Powerful sky. Heartily applaud the far bank and trees angling towards an off-image vanishing point created by the benches and posts. Some folks might protest the subtle frame: I like it. Maybe I, personally, would have cloned out that teensy white box on the water between the 2nd & 3rd posts, but certainly it is nothing that detracts from the overall impressive impact of this well crafted B&W. Good luck!
