picture

this picture? I think it’s a kind of art. A character,like pokemon, is made with vegetables or some ingredients. Confusing

I think the picture is a style of art that creates a character, like Pokemon, with vegetables and other edible ingredients. Maybe?   

It looks very cute and interesting, so children who wouldn't initally eat vegtables could enjoy them. (your sentence was grammatically correct but repetitive)  The box is cute too. Sometimes, “Hello kitty” and “Pokemon” are printed on Bento boxes. There are net shops that sell many cute Bento goods. 
Secondly, the nutritional variety is good. If we go out for lunch we choose our favorite foods (sounds better). I prefer meat, so I pick oily foods for lunch. However, it’s bad for your health. A sandwich or bread is good, but there is not enough vegetables, meat or eggs. On the other hand, when Japanese people make bento, we think about nutrition. Usually for bento, the ingredients consist of: rice, vegetables, meat, eggs, and frits. A Japanese bento is good for your health compared to some lunches that we buy (Americans don't say "lunch that we buy outside" because unless the food is made at home all lunches are bought outside ... we ususally just use the phrase "going out for lunch"  there are resturants and street vendors...so you could say "lunch bought from street vendors or at resturants") 
Thirdly, is the effect bento has on animations and comics. A subculture like animations and comics is popular among not only Japanese people but also non-Japanese people. Through bento, non-Japanese people learn about Japan.In comics, some characters eat their bento at lunch time and Non-Japanese people are interested in it.
In japan, usually a woman makes bento for her family in the morning. It’s not that special unless she uses kyarabens. (Why? are Kyarabens special?) However, many people are surprised. Japanese women who make bento are encouraged and happy because of the unexpected reaction. Based on their reactions, they changed their thinking that a bento is not special.

Great!  I learned about bentos!
