That's a Teasel, That is!

I have this picture of a teasel. It's not very interesting. So I PP'd it in 4 different ways. I'm interested in your thoughts on whether the PP works? Pictures link to flickr for BIGGER images.
Thanks

Upper left is by far the most appealing. Warm and natural.

I agree....but all of them look nice!
