Leaf Veins

This week's prompt is "Pattern," and as I check my photo folders, I realized I don't have that much images that depict patterns, but I think this one would pass up as a "pattern" image. :)

I took this at the Touch of Glory Prayer Mountain in Antipolo last July. While we were looking for our own prayer hut so we could reflect and contemplate, I saw this huge fallen leaf (it looked like a maple leaf, but it wasn't maple... and it was so big I can use it to cover my head if it rained) and got attracted with its veins.

Something was "wrong" with this image - the lower right corner was too dark, while the upper left corner was too bright. Any suggestions how to fix that?
