That's some strange illustration for the Demon there. Air brakes and canopy open while the pure bird is trying to take off !!!!! I hope there is still time to correct it.
For both landing and takeoff, the canopy (at the time Demons were in use) was left open to facilitate a quick exit in case of ditching - a practice left over from the prop days (and before ejection seats.) Because it was a sliding canopy, it was still possible to fly with it open. Not possible with clamshell type canopies.
The use of 'speed brakes' was to increase the drag, allowing for a higher engine RPM at lower speeds than normal - this was due to the slow engine response. Keeping a higher 'power' setting improved the response time during landings.
In the illustration, I would say this is a 'bolter' but the tailhook is not visible, so that is the only inaccuracy in the artwork. I'm not familiar with the Demon's tailhook mechanism, so it is possible it had already 'retracted' so I can't really 'ding' the artist on that specific point.
In fact, this is probably where the artist got his/her 'inspiration':
