Thanks, Bob. You read my mind!
I like your idea.
Here are some of my ideas or suggestions:
For a horror / Halloween theme I would make the image abit darker and use cold color tones. I would use more blueish color in the shadows to emulate how things look at night / dusk.
I took the liberty of doing a 5min edit in PS, I hope you don't mind. It is not the final product, I just wanted to show the concept and my idea.
Looks like its time for some off camera flash...the lighting needs some contrast to give it some real mood.
Great picture! One thing I would do: position the model slightly to the right, so her head is not intersecting the window sill...
RPT: Thank you, you are correct that the photo is slightly off compositionally. I'll see if it can possibly be fixed with cropping, it's just one of those things... I still think the photo has promise, but it certainly could have been better if I took a little more time with it. You know how weddings go, quite a hectic day. I'm not sure about lengthening the knife, but it is something I will certainly try out to see how I feel about it.You are very welcome. Don't get me wrong, the picture has promise. A few tweaks and I am sure you will be happy with the outcome. About the knife, that comment was for any such opportunity in the future. I did not mean for you to edit the knife...
