Shooting trees from below

[EJC]

I was reminded of a problem I have by Mad Aussie's post this morning Silhouette
What should you do to capture tree canopies from below. In this photo I liked the gnarly branch silhuette and the orangey red flowers. But the photo isn't nearly as interesting as the image I saw. Would it have been better shot with a wide angle lens, compiled as an HDR or is it the seeing in 3D and capturing in 2D problem? What would improve this photo?

1/125, f9 ISO 320, 28-135 mm lens @ 28mm on a Canon40D

Thanks
