Spring Flower Show at the local Conservatory

I'm a bit nervous posting here with all of you wonderful photographers. But I'll never learn if I don't share. :smile:

Here are a few shots I took with the Tamron 28-75 f/2.8. It isn't true macro, but it's the closest I have. I had a hard time metering and ended up with a lot of blown highlights. How can I avoid this in the future but still get the correct subject exposure? I am open to all comments and critique! This is my first attempt at macro.

These were all taken at 75mm with spot metering and sunny white balance.
