Firstly the latest version - 2.4 - is great. The Asset Library is especially useful. My only issue is the people are somewhat limited. It would be very useful to have people with a greater variance of age and ethnicity. On larger projects there is a need for more variance otherwise we end up with repetition.
We often work in London on large public projects. Our clients are always interested in seeing visuals that represent the reality of the city's diverse population.
Beyond that, great work.
