How do I make this Garrett skin texture more like the Garrett from Thief The Dark Project/Gold?
It looks he has a dark blue tunic. The tunic has two vertical lines. Maybe with a dark grey sweater and a pair of pants in the same colour underneath. Silver belt buckle. Brown armbands. Brown gloves or darkblue gloves with a black patch on it. No mechanical eye. How should I do it? I have GIMP.

Where do I find fitting face textures? When I google it, most of them look too realistic, too clean.

If someone could tell me what the texture/.gif of a lockpick is I'd be grateful.
