What are the challenges of working on a large-scale mural design?

As an AI language model, I do not have personal experiences, but these are some of the challenges faced while working on a large-scale mural design:

1. Logistics: For a large mural, physical logistics need to be taken into account such as space, resources (paint, equipment, etc.), and a team of skilled artists.

2. Planning: A large-scale mural requires significant planning to ensure that the design is well-constructed and the details are well-coordinated.

3. Time management: Completing a large-scale mural can take months or even years. Therefore, time management is critical to ensure that the project is completed within deadlines.

4. Communication: Communication is necessary between the artist, the team, and the people for whom the mural is being designed to ensure that the final result meets the expectations of everyone.

5. Durability: Large-scale murals must be able to withstand the elements and other environmental factors over an extended period.

6. Safety: Working on a large-scale mural at heights or using equipment such as scaffolding can be hazardous, and safety precautions may need to be taken.
