Japanese flower gardens. Portland, OR

Would it have been possible to have taken this from a higher vantage point? To my eye, the strongest part of this photo is the path, both it's wandering course and as a separation of the flower beds. I think the image would have been more visually striking if the pathway was bolder..

Where is this in Portland?

The garden is in Washington park. Take the MAX out of downtown westwards, and get off at washington park. There's a shuttle bus which will take you to the garden.

The beds which are low and red in this picture are full of irises, which bloom quite spectacularly in summer, as you can see in this picture I took on the very path that is shown in the above shot: http://www.photo.net/photodb/photo?photo_id=494762

The above shot is quite pleasing, but I think the reds seem a little subdued, in comparison to the popping green of the foreground. Perhaps a slight drop in the saturation of the greens would balance it a little better?
