I might find your chosen DOF a bit shallow... The flower is beautiful, there's no denying. But I think I would have liked to see some more in focus, like the one right next to the sharp one, too.
i would be very interested to see what a green filter does, what does a green filter do to such neutral tones? just make them green? or is that to simple to sound intelligent!
Oh and here is how to do the signature... basically read the thread.. I ask the same question and then the answer is posted in another link provided to me by Hobbes. So first use a sharpie and write on a white piece of paper, scan it in and then after I scan it in, in the thread Hobbes tells how to cut it out. If you have more questions feel free to ask
