This is really just a “script based” punk. I used Manuel’s MakeHead script, and the Fiber2.02 script. Suggestions on making it more realistic?
Hey this is good so far, but IMO the spikes should be more pointed.
For some more realism, try to Yaf him 
See y@,
Serialsiner.
Ears, nose and neck need more detail. how about some facial hair/stubble?
Looks good to me! I agree about the spikes but I like the textures.

i like the spikes, but not the ear.
yes, ear is not good … 
… maybe a bit uv would not matter … the lips a bit red … and some more lil hairs round the eye
eyes general …
The hair looks awesome!
For more realism… hmmm… that ear is a bit odd… More piercings too, a few on the ear, a nosering and maybe a labret spike (just below lower lip)?
The stubble on his head looks a little er… “strong” (maybe a bit too dark and long?). All IMHO of course.
Killer 'hawk, dude, but I agree, to be authentic the spikes need to be slightly more dangerous looking. A touch of acne couldn’t hurt, combined with increasing the specularity slightly. Also the hair itself would have some specularity due to the hair gel. A tattoo might look nice too. Oh yeah and he might well be stoned, in which case his eyes would be more red. Also, I think the ear is pretty good, but I think a touch of cartilege at the bottom couldn’t hurt.
