I've employed these graphics in one of my projects...
I've builded them on TWEWY mugshots (credit to Ragey for ripping... Spriters Resource is one of the best site ever:)).
If someone is interested in using them, just ask for permission and give credit to me (mandatory).
Here are the mugshots:
Mugs - part 1
Mugs - part 2
Mugs - part 3
I don't want to find someone claiming they have made it by theirself.
If this is the case, this will be the last resource I'll post.
Please, post feedback and impressions, I'd like to know what do you think of these:)
Hope these can result useful...
