Actually, the only problem I encounter with macro photography, using a simple camera, is to get it in focus. If you look good, you'll see that this photo could still be a bit sharper. Apart from that, it's easy.
Mind you, with a more advanced camera, getting it in focus is much simpler, but I prefer a lightweight camera. My pack is heavy enough!
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
