Hey! It's pretty spectacular to me you live in a place where these (for me) exotic cacti grow! I never see them 'in the wild' although it's now considered very hip to have tiny ones in tiny terra pots in your home, haha!

Anyway, as soon as I see a lot of textures in a picture I tend to opt for a bold black and white in order the emphasize those textures. Your picture sure does have a lot of different textures and/or natural patterns! So here's my bold black & white edit :-)

Cheers!
