It seems to be a very old leaf. That's a wunderfull effect. Well done. Thanks for sharing.

Your border makes it look like a box you unearthed, opened it up and viola - a old, magical leaf. I wonder what it'll do? Nicely done, I like the effect.

I really like the border around it, makes it very interesting.

The border goes well with the monochrome effect but the subject is lacking substance!
