Just came across this farmer portrait while passing by a village which we then visited, Fanzara. Apparently it's known for European artists to come here to do building size paintings, and has become a local attraction in the area. The whole village is like that, quite lost in the mountains. Can't imagine the challenge of going that big. I guess you need a special proportional divider to keep proportions ?

Silo and water tower art is gaining popularity in Australia and I think it is done in USA as well? There are tourist trails which take you from silo to silo around Australia.
The perspective must be a nightmare to sort, let alone the execution!
Wow, these silo paintings are very impressive. Yes that must be quite fantastic for those kids living there. It's magic
The doodle grid method can be applied to paintings and drawings of any size. Gets away from the tedium of regular grid work.
In Procreate the doodle layer can be sized and rotated to fit the image and a new combined doodle/image layer created so that work can be shared and proceed over days and weeks without having to set up each session.

I agree about getting away from grid methods. I usually go free hand, that's why I was wondering about the method for large size. I have no intent to go mural soon though. But I'll remember that when the need will come 😉.
That kid painting is awesome, he must quite happy to become internationally famous !
