Changes in the Mantis world from ancient times to modern times

<1st to 2nd> The ancient strong Mantis era (before the Showa era) In the past, the world of Mantis was full of nature and fierce warriors. They hunted all kinds of prey in the forest and devoured their blood and flesh, gaining more and more power. <3rd to 4th> Recent Lorimantis era (Heisei) However, as urbanization progresses, it has become difficult to secure food in the forest. Therefore, they evolved to make their bodies smaller so that they could survive on less food. Energy saving was required rather than strength. <5th to 6th> Modern Chibi Mantis era (Reiwa) As they are no longer able to be self-sufficient in the forest, they stop obtaining food on their own, and begin to evolve into adorable forms that allow them to receive food. get chocolate https://www.aipictors.com/works/273018/ become an idol https://www.aipictors.com/works/279836/ I am enjoying my happy Mantis life♪ I was trying to make a cool Mantis monster in monochrome, but why did it turn out like this?
