wow, very realistic...great job!

very nice super realistic work...gl

I love the texture on the cigarette, but the flame looks disproportional to its size. Additionally, that is the only lighter I've ever seen that could light without the button being depressed.

First of all congrats on a realistic image.
1. I realize that you're not a smoker so good for you
2.Every cigarette has lines on the paper so that it would burn uniformous - those lines are actually where the paper is thinner.
Check this: http://static2.bigstockphoto.com/thumbs/1/3/2/large2/231722.jpg or any google image.
3.Flame can have any size but it will have a continuous shape, even if the wind blows, it will just bend without loosing it's integrity. In that position you would burn your thumb

4.There are lighters that don't need the button pressed to light up, but that is not one of them.
Anyways, it's one of the best renders around. You can still improve it, or use this info for another contest.
