Michaela Mila Pala We used a similar shot for a presentation rendering/cgi of a chair we designed, but I like your shot much better, the camera angle is just perfect. I wonder if you would give us permission to use it :-)

Dear Giovanni Pellone,
Thank you very much for your invaluable feedback!
My current employment does not allow any side jobs, thus, unfortunately, my hands are tied. I've enjoyed screening the place, sense the atmosphere while thinking of the right angle and I am glad that I can pass that excitement to viewers. That motivates me very much to continue.

Michaela Mila Pala That dark hole that beckons...I love this photo.

I did notice that the part of the hole just above ground level is slightly lighter than the rest, so I darkened it to make the entire hole look completely black, and also added a vignette around the edge of the entire image to focus the eye to that blackness. I think it makes the image even stronger.

Thank you very much for your suggestions!
