How long did it take?

The BBC (UK public service broadcaster) runs an annual portrait competition (see this YouTube trailer for the 2019 competition).

Any media is permitted (oils, acrylics, pencils, PC apps, etc.) In the competition, artists are given just 4 hours to create a likeness of a model (usually someone famous to UK viewers) but when asked how long it took them to create their 'audition' submissions the artists usually respond with a time between 20 and 40 hours - sometimes much longer.

I can only imagine this took much longer. Great job.
