None of these pictures are quite how I imagine him, because from the
very beginning I thought he should be played by Lee Ingleby, the actor
who ended up playing Stan Shunpike. At the time I drew these, I was
no good at caricature, and also had no readily accessible reference,
so I made do.
Troll in the Dungeons! - A little faked
adrenaline can work wonders.
The Power of Luuurv - Quirrell recoils in
pain from Harry who seems, somehow, to scorch him terribly. (old, boring
design)
Portrait - I came up with this design
while in line at one of those Chinese buffet places. It was quite fun
to draw, and probably the reason Quirrell has so many pictures, for
such a minor character.
Adjusting the Turban - My, how Voldemort
chafes.
Evil Snap - Here's
Quirrell summoning the cords that bind Harry. I like the motion
in this picture; I can almost see it moving.
