These aren't all that bad. The main thing here is highlights, and keeping them under control. The light seems a little harsh, some fill flash would help (or a diffuser). Here's a couple ideas...

- Spot meter on the white part(s) of the flower and bring up the shadows during pp

- Go manual and get a reading from an object that is 18% gray and in the same light
