Sweet Cyanide

Ok, here is the deviation I promised you.
I know you guys are probably wondering why I put this into the macabre and horror section. Well, I put it here because as you can tell, the title is Sweet Cyanide, aka a deadly poison.
Yesterday, I was sitting in the doctor's office wondering what color cyanide really was. I mean, it has the word "cyan" right smack dab in the middle. So I drew this. I really wanted to put in a skull and crossbones or maybe a radioactive sign, but, meh, I'm lazy.
I actually really wanted to place this under vector, but it said "Absolutely no photoshop burshes." So I was like, "......Bummer."
Brush (yes, only one brush): [link]

Time: give or take 3 hours in between watching Heroes and Dancing with the Stars (I voted for Apolo btw)

Advanced critique because this is the first piece I've actually really liked in a long time, and it came out almost exactly as I hoped. I've tried to get this style for so long (see Orange Again) and I finally did it so I'm really happy.
