Having an objective score is quite difficult. Maybe it would be better to do a pairwise comparison and calculate ELO?

Just click through the models. At a glance (and highly subjective) I don't see anything jumping out as oom worse than anything else. I only noticed a model placing the animal inside a plane (with seat and small window) but other than that, they all seem similar inside each model to me.

If you want to, go ahead, but it seems to me the author already exceeded the energy expenditure that this question warranted.
