Fail Fern

So I've been working on this fern plant for a little over a day now, and somehow the normals on the leaves went weird and I don't know how to fix it.  I had to flip the model 180 degrees to fix this while transfer mapping but it doesn't have the same look that I wanted.  So I'm scrapping this for now until I have a better idea of what I am doing with normal maps, maybe try something simpler for next time.  I didn't do any work on the diffuse map, it's simply one colour for contrast purposes.

The high-res version of the leaf:
