Yes, it is a quality pic, except....

1 - The aircraft wheels aren't chocked, thus breaking standard safety procedures
2 - The mechanic is working alone without a comrade to watch for persons or objects liable to interfere with the propellor and/or suffer from propwash
3 - There is no fire extinguisher present thus any engine fault causing a fire will result in a lost airframe - and if the aeroplane is armed, possibly worse
