my first attempt at re-skinning a model.
Theres also a backup copy of the original gman skin in the .zip file, so if you get bored of the skin or dont like it anymore, you can just delete the reskin and rename the backup.
Things I changed:
-made the suit red. (dur)
-changed the pupil to a dark gray.
-made the suitcase black.
-made the tie black.
extract both files to "garrysmod\garrysmod\materials\models" folder.
