My advice when folks are struggling with writing in the third-person omniscient is
to Lemony Snicket it up. Give your omniscient narrator strong opinions
about what’s going on. Don’t fall into the trap of assuming that the
third-person omniscient perspective must also use the objective voice;
those are two separate things, and many of the most popular and successful writers who’ve written in the third-person omniscient do not, in fact, use the objective voice.
If you're interested in more dinosaur comics with a decent amount of shrink-wrapping and lack of feathers, but interesting nonetheless, check out "PALEO" by Jim Lawson! It's similar to "Age of Reptiles", but it's in black&white, and it also has a omniscient narrator! (Don't worry, it's not WWD 3D!)
