It's definitely not an E-FIT, which as the name suggests is a likeness assembled from various facial features - hair, eyes, nose, mouth, etc. on a computer screen, although in its infancy was carried out with paper/cardboard cutouts, as I recall.
The pencil sketch was done by an experienced amateur artist, who I feel actually saw this mysterious person in reality, or by a professional guided by the input of Jeni Weinberger.
This OU video of an attempt at Judi Dench's face shows how poor E-FITs can be...

I don't care who did the sketch or whatever you care to call it. What I do know is that she isn't mentioned anywhere until this efit is released to the press. Despite attempts by Dave Edgar to link her sighting and the efit with the sightings by Tasmin Silence and Derek Flack, they produced different efits from her and from each other.
Scarface witness: Police ignored me The Sun

A WITNESS who sparked the hunt for a scarfaced suspect in the Madeleine McCann abduction has NEVER been questioned by police.
The woman twice saw a man dubbed "Mr Ugly" loitering near the McCann holiday apartment before Maddie, three, vanished.
She reported the sightings to British cops when she returned home from Portugal, but they failed to follow up her lead. It was only when she received an emotional phone call from Maddie's mum Kate, 41, nearly two years later that a photo-fit based on her description was put together.
The angry mum-of-two, 36, who has asked not to be identified, was in an apartment three doors from the McCanns. She said yesterday: "I feel vital time has been lost. Every day I hope Madeleine is found safe.
"When Kate asked me to help, I agreed immediately. But the police should have asked two years ago."
It was only after Kate got in touch that the woman learnt two other witnesses saw an identical man in the resort of Praia da Luz in May 2007. She said: "I can't believe our three sightings weren't linked earlier. It took the McCanns to do that."
The weirdo so unnerved her that she pulled her three-year-old daughter away. Back in England, she told her local police in Wiltshire.
They passed her report to Kate and Gerry McCanns' local force in Leicestershire. She said: "I heard nothing from them."
The woman who featured in a TV documentary about Maddie last week, finally gave her description to the McCanns' own investigators.
