The quality of the image and the effects are a little muddy.
I've got a particularly dark, damaged monitor too, and the background's pretty unclear to me.

Quality aside, the execution seems decent enough.
It makes sense that Smoke might employ this kind of attack, but I wonder how well thought through it's been. Could maybe be a little more original, and interesting than a jet stream of smoke.

The background feels a little slap-dash, too.
I'm not quite sure what it's supposed to be.

Not bad, but could use some creative work.

My first bit of advice is this; if you have to explain a fake, then you've worked too hard. A fake should be self explanatory just at a glance. You can add a few things in there that people might catch after looking once or twice, but the main idea should present itself in the image, not in a description below or above the image.

If you are going to make something complex enough so that you can't tell what happened, animate it instead of giving a story.

The effects look poorly done, and the sprites are just ripped straight from the game. Not a major thing, but edited sprites show more <3.

The background doesn't look very good either.

Overall it's a mediocre fake with bad effects.

Okay, the effects are poorly done and so are the sprites. Also, the text on the lifebars is too small. There are no win marks and timer is missing, too. 1.5/5

Yeah that, and that smoke wouldn't kill you if was thrown at your head. Unless you sufficated. Plus i've seen this idea a billion times! The only thing that wasn't bad was probably the backround.

2/5

4/5 doesn't look THAT bad
