Humanity's Nightmare

Just something I tried to draw in less than thirty minutes (pretty much a fail right now ) About a nightmare i had, and I've been trying to figure out what the meaning is behind it so here's what i have so far.... Warning: it's going to be pretty... meh...

The faces represent different emotions I've been feeling, or will be in the near future, sadness, anger, close to tears, and so on (i'll probably add more faces later). There is a fire in the background, represented by the smoke that entices some of the heads, the fire representing the suggestion of chaos, or trying to cause it. (recently I have thought fire as a type of hope or the will to do something.) With the faces in this manner, some emotions over power each other, and as you can see, has turned the picture into a dark, chaotic, mess. Also, the dark decrepit looking hands on the heads in the middle-ish area symbolizes a desperate need to break away or maybe longing for something....
By the way, the waves are also a different form of smoke, that I'm not sure about yet...

So I was thinking that to people with power (government, dictators, etc.) this would be a nightmare to them, if their will (the fire) caused them to go in chaos, not sure of what's going to happen next.

So yeah, hope you like it, I'll hopefully make it better soon ^^ (note: this is actually only a part of it, it's just that I had to crop it down since my hands kept shaking so I couldn't get a steady shot And of course the original looks better since I used pencil and camera's never really do a piece like that justice )
