You could add the smoke and embers in Photoshop. Then the smoke alarms wont go off and you wont get sick.
Smoke alarms don't usually go off that easily. If you're standing underneath it then yeah. But if it's a little way from the alarm, and you have ventilation then it shouldn't go off. Especially if the whole thing isn't being smoked and exhaled.
However, you often have to suffer through things that you would rather not in order to get the shots you need to make your work what you need it to be.
Look at fashion models, they often go through hell to get the shots right.
IMO, having to suffer or experience something during the process of your art makes the work that much more personal to you.
Makes you care about it more, and makes you want to get it just right because it reflects YOU.
You don't seem to have that connection with this project. If you did, you wouldn't be satisfied with this.
As it stands, you set a couple 9mm Luger shells up, threw in a cigarette and snapped the shot.
The aesthetic value is there as the colors look good and the contrast is decent, but there's really no message coming through.
It looks more like stock photography.
There's also no real composition going on in the image, which adds to the stock photo appearance.
If you put the burning cigarette laying flat coming out of the right bottom corner, leading to the shell casings, that will give you a little composition.
However you do it, you want to guide the viewers eye toward the focal point of the image, ie..the burning cig pointing toward the shell casings.
If it were me, I'd smoke some of that cig and get the ash real long, then prep the shot right so that there's alot of smoke lingering in the air.
I hope you don't take offense to me pointing these issues out. I'm just trying to give some constructive criticism which is very important to developing your skill in any artistic endeavor.
Don't get defensive, because you'll get alot of critique over the years should you choose this as a career.
