Texture shouldnt be too tough to find... Eyebrow shape would be important I think.. other than that, just basic caucasian colouring, maybe a little on the pale side, with more stubble in the mustache area than the beard.  I think there is a matrix type hair floating around if you are looking for that exact style.. but you could probably get away with a lot of short hairstyles.. depending if you want a 'Neo' or a "keanu" lookalike
