Macro photos, take 1 - flowers and bees

I recently bought a Canon 100mm f2.8L macro lens and have been dying to try it out. The following are a few of the ones I took in Yuye's garden - can you believe there's no other flowers? I was so excited the day I got the lens that I ran outside to find bugs and flowers but, there were none! I couldn't even find ants! I had to settle for this flower (which really belongs to the next door neighbours) and a few days later, I found bees near one of his trees. Let me know what you all think and maybe give me some pointers. :)
