What are the limitation of these facial reconstruction?

Facial reconstruction techniques have several limitations, including the subjective nature of the process, which can lead to variations based on the skill and interpretation of the artist or technician. Additionally, reconstructions are often based on incomplete or degraded skeletal remains, which may not accurately represent the individual's unique features. Furthermore, factors such as soft tissue thickness, age, and ethnicity can be challenging to accurately estimate, potentially resulting in misleading representations. Lastly, these reconstructions may not account for changes that occur over time, such as aging, which can further complicate the accuracy of the final outcome.
