Most of those photos look great, My favorite ones are first three. But I have a hate relationship with hornets and others flying and stinging things. So after meeting one so huge I would probably run away.😛
They are real artworks in my eyes and using black and white is always an excellent idea as it takes away the distraction.
I am not a photographer. But returning to not colorful art after all those years is both challenging and interesting. When I started making art I only made a few pieces without color. But now when I started making manga I think that black and white works kinda stand out in their own unique way.
