Utahraptor: surprisingly knowledgeable on Greek mythology. Well done.
T-Rex: conclusions might not be so far off base. Avoid informal language, and the phrase "super sexy". And I guess "sexed up" should be avoided too. But "cheezed" can stay.
Dromiceiomimus: that student who never speaks, but rather anxiously keeps their heads down to "be less noticeable". I see you there, Dromiceiomimus, and I'm calling on you as soon as I figure out how to pronounce dromiceiomimus.
