Aid me!

So for Halloween I am running a 50/50 Jekyll and Hyde split.
I have:

Long Sleeve white-button up shirt
Black slacks
Sweet old man vest
Psuedo fancy black dress shoes with big metal squares
Fang(s)
Artist Charcoal (for dirting up the stuff)

I am going to make the left side look a bit roughed up and untucked.
I am going to cut up and raggedify the left sleeve and left slack.
Dirty up the left side of my face and leave it mostly unshaven and wear one fang.

Any suggestions to help my costume?

An evil cackle/laugh. o-o;

Get a coloured contact lens and stick it into one eye, and try to make one side of mouth crooked or something. Though you'd have a cramp after that.
