The Essenes and the Nazarites did wear their hair long, . . . and there is evidence that Jeshua bar Josef. called the Christ was both. Just because Saul, later called Paul, had a thing about applying arbitrary rules, which Jesus said he came to replace, does not mean that Jesus did.
Jesus was not a Nazarite because he drank wine. He was not an Essene — won’t find it.
Judas was hired to identify Jesus; there was nothing different in his appearance.
The Jews, when they prepared a body, wrapped it around with cloth, etc., and did that with Jesus, except his face, for lack of time. His body was covered up.
If you will notice, that shroud imprint has his hands on his knees, which meant the body was kind of in a seating position to accomplish that.
