I find curios that Astra's pelicans are basically the same (yellow sun top right corner, green bike, same bike shape, same legs style, very similar background) while in other there is more randomness.

This tracks with what OpenAI has been saying about Astra: that it tends to do things in a certain way and it’s up to you to prompt it to change its style.

Astra is the only model that correctly depicts occlusion of crank and leg, although interestingly, at max and medium levels (not in between).
