the poster boy has other pics up on this site, unfortunately i do not recall his username. if memory serves me correct he has a very natural look and it does not appear as thick as the piece being discussed in this thread...
additionally, the guy at the top you are referring to either looks younger or actually is younger. age does play a role in density as well as other factors.
you are also going off of small pic that is up there....

the guy at the top also has what are called curtains, that is when hair is used to cover up receded temples. now picture him with super thick, almost straight across hairline meeting his actual side hair in the before pic. it completely changes the look.

do you think that antys piece is not to thick? do you think there shouldnt be graduation in the hairline? do you think that the shape of the hairline is age appropriate and matches his side hair good? do you not think that the photoshop pic looks better?

when wearing hair in most circumstances less is more 80-%100 density...keep in mind that one sellers 100% can be more like 150% if using a different scale...it falls, flows and just overall looks better.....overly thick hair is one of the biggest giveaways...unless of course one is quite young and has good side bio and temple hair to pull it off, even then seeing some scalp is a good thing....
IMHO
