I like B&W for this. Good comp and 'movement'. May be a tad oversharpened? I know this isn't your fault necessarily, but the two objects in front of the goose (leaves I guess?) really do grab some attention. Just some observations. Good luck.
I love the BW conversion. Terrific contrast and wide focus. The texture of his feathers is great - almost like a pin and ink. The composition is good. Love the diagonal line connecting all of them together. Is that fish to the left? turtles? other geese? LOL Doesn't matter. I love it.
