Liz lovely colors in your flowers with the sun washing over them it certainly brings out the detail.
Take it or leave it Liz,

but in my experiences with Sunrises and Sunsets I have found for best results, you wait until the Sun just Peaks out over the Horizon, and the Sunset is best when it has dropped under, well I have found this, and it has worked great for me.
An Example, the first: Sunrise, second:sunset
