It was a cool class, though it was years ago ha. We could use any medium we wanted (oil, water color, charcoal, etc.) and the premise was using science reasoning to make the fantasy art more grounded to be believable. So one assignment was create an alien landscape. We had to think about the ecology of an alien planet and how the creatures would evolve there and try not to think of our biosphere if we could help it to make it more alien (this is really hard to do). In the case of Godzilla 98 he followed the route of an iguana and see how it would mutate and then added feline features (snout and body composition) while using some of the elements from classic Godzilla. To be fair the classic Godzilla design was based on a man in suit so it made sense to go from a different angle in CGI. But alas us G fans are a fickle bunch and like our classic design lol.
