Help the MPD with your Graphical Skills

Okay, I admit it. My strong suite is not doing graphics, it is dealing with data. That means I need help on the graphical side. I need some better looking icons for our maps to denote the following:

Burglars
Parolees
Sex Offenders
Warrants
Felons
Scofflaws
Gangsters

I created the icon below and I think it looks ok, but I would much rather have someone volunteer to do some custom icons for the MPD's maps. If anyone out there woujld like to volunteer their talents . . . I would love to take advantage of your skills. I've always heard the "form follows function". Well, the functionality is there, but I think the form could be better. Anyone interested in helping?
