Ouch! I have so many bad memories of cactus plants! My Gran had a huge one potted in her hallway, we would sit there and play board games as kids and the number of 'spikes' we pulled out of our little hands and toes is unbelievable! You've captured it in all it's horrifying glory well here!!!
Terrific focus - you can almost feel the sharpness of those spikes. More than once I've misjudged how close I was to a cactus when taking a close-up. Finally became more wary. Love your lighting. Fav
