His work definitely shows that close-up perfection is not always important. His overall sculptural look is very professional. And close-up perfection will tend to eat a lot of time, along with adding a lot of weight and expense. For something without space to store them, and would be discarded, it certainly would be a waste. The extra energy and money may be better spent on creating other things.
If you wanted to see more of this guy’s dino haunt, I stumbled upon this family’s video at halloween time and lo and behold it included video of the Utah guy’s dinosaur themed yard (plus a bit more of his King Kong from the prior year). Nice close ups at night with lighting and with fog and also video taken during the day. This starts at 4:55 into the video.
Same family, video of the Utah man’s prior yard builds including ghost train, pirate ship and King Kong. Surprised I don’t recall seeing his yearly yard haunts before. The yard tours start at 2:03.
