This is your entry into the Delicate challenge and at first I had to smile as I have been trying to quit those evil things!
Technical:
You haven't included any information or editing details with this image, so I will have to try and guess what steps you may have taken to get the finished result. To start I think you have cropped this quite tightly and used side lighting plus an on camera flash? The side lighting has created a long pale shadow on your background. This does not detract from the overall effect though. The side lighting appears to be a table lamp or similar as it has given the image a 'nicotine stained' brown tint. Focusing is bang on with good DOF. A very good technical image.
Composition:
The tight crop cuts out any blank or negative space. Although some will say the backgrund is dark, I think it fits the theme here. The eye is lead around the photo.
Overall:
A harsh, ironic look at one of the worse habits many have, and treated in a humorous way. The focus is excellent, but the one thing that jars for me is the shadow under the skull. The cigarette packet is a neat twist as I assume the name 'Delicados' means delicate...not a very apt name for something that can kill you in the most painful ways!! Most voters would miss such a subtle hint as to the title and I think this could possibly have accounted for the under 5 score. I would put it in the 6 to 7 bracket. I hope this is helpful and constructive.
thank you for not centering the objects. nice lighting. the background appears a bit darker than white but this may have been intended. it works well with the theme.
Wow this is a very good picture. It sends an interesting message. The picture is very clear and sends out a good message that smoking is a habit. And how the skull simbolyzes that life is delicate. That is Brilliant! I understand your message but others may not. Next time, maybe try something easier, simpler. Otherwise than that, AWESOME PICTURE!
