Really great idea! In a macro such as this, it might be wise to have that lady beatle in sharp focus so it gets the attention. Overall, I like the atmoshpere and light in this image, and the point of view.
I like the soft yellow color and choice of flower. Ladybug is positioned well. I think this picture could be improved with a bit more "punch". Perhaps more contrast or saturation, I'm not really sure.
I like how the lady bug doesn't take away from the flower being the subject; it definitely adds to the image. The colors are a bit soft, but still pretty.
