The way everyone gushes over Xi in these pictures (and laugh at his jokes) is the most leader-cult thing in the set, and given that Xi is the leader of the great and successful Communist party of China that is to be expected. Hua could be pretty informal and push the leader-worship off on Mao or the Party. Xi has to be both a symbol of Chinese greatness and an ordinary Jiu. It's a hard act to pull off, and it will be interesting to see how well he does at it. God forbid he ever ends up in a picture like this.
Offbeat China has some official cartoons showing Xi Jinping as an ordinary guy who can sit cross-legged just like folks. I guess now that Gary Locke has officially left the building there is an opening for someone to take on the role of high official who is one with the common people. The style of the drawings is pretty obviously intended to make him look like an ordinary person. They remind me in part of some of the old shots of Chiang Ching-kuo, who never tried to pull off his Dad's spartan military style . Nor did he try to pull off Wei-guo's full-on Nazi look. Rather, while democratizing Taiwan, he chose to look like a man of the people. What the Xi Jinping cartoons remind me most of though is Hua Guofeng. As Mao's chosen successor Hua had some big shoes to fill. And he did this in part through a massive propaganda campaign, which you can learn about at Chinese Posters. Here we have Hua cleaning a counter and Xi getting his own food. Hua is serving the people, and Xi is being served by them, but times do change, and waiting in line will get you credit as being a man of the people as a Chinese official today. There are plenty of shots of Hua holding a shovel and such like, but China's leadership has changed so much that that would just look ridiculous with Xi. Instead, he meets with college students (the future elite) and encourages them to be concerned with the common people. Hua probably would have done that by leading the students out for some vigorous physical labor alongside workers and peasants, but this is 2014. Both of them mingle with the common folk, and you can see some of the differences in revolutionary charisma. Part of it is the cellphones, but also it is hard to imagine Hua greeting a member of the masses who happened to be female with "Hello Beautiful." Hua had the disadvantage that he was following Mao, and so he had to either put himself in Mao's place in the picture, or sort of abandon Maoism, neither of them a good strategy. Hua was followed by a guy named Deng Xiaoping, who shied away from the leader-cult thing, and when he did turn up in posters they would focus on him as an individual, someone passing through revolutionary history, not dominating it.
