For anyone that's confused; S4 Will Byers REALISTICALLY speaking, would NOT look how he does in the show due to Noah Schnapp aging faster than the character. Because of this S4 Will Byers would actually look more like S2 Will (hence why I used my S2 Will Byers design for the last part), MAYBE a little bit older.

Sorry for any confusion or if this (or the video itself) just didn't make any sense.
