I must admit I'm not the best at making Caillou fanart or drawings of Caillou, and some other cartoon characters, but I will not give up, at least not yet.
I will make this in the form of galleries.
Standard Caillou Fanart (Basically regular artwork of Caillou)
My very first attempt at ever drawing Caillou.
My first full-body drawing of Caillou.
My first drawing of Caillou in his cap (as shown on TV) and my first drawing of his sister Rosie.
Caillou at a railroad crossing in Canada (the country in which Caillou takes place.) And something I would have loved to see in the cartoon, but that's okay.
Drawings of Caillou on one picture. I tried making Caillou in his real style but then I experimented with my own style, which I think turned out better!
Another attempt at drawing Caillou in the real style (this is supposed to be the As Seen on TV style) Caillou asking people how they're doing.
Caillou in my style and posing with his legs crossed and his arms folded.
Caillou flying (although he cannot fly, just artwork I did.)
My style of Caillou, Caillou wearing a white T-shirt, blue long pants, and saying "I Love You!" even to his haters!
Caillou and his family, Boris (Daddy,) Doris (Mommy,) and Rosie (sister) and a passenger train (based on the one seen in "Caillou's Train Trip." https://www.dailymotion.com/video/x2nyoj6) This is also my first drawing of Caillou's parents!
Caillou, his sister Rosie, and three of his friends Sarah, Leo, and Clementine near a Via Rail passenger train, the national passenger train for Canada.
Caillou older/ aged up.
My first attempt at making Caillou as a teenager. Also my first attempt at drawing Rosie as one and my second drawing of Rosie. Caillou is 16 and Rosie is 14 in this picture.
Another attempt at making Caillou as a teenager, and I did more than one drawing. I tried to stick to the TV style (although Caillou is never shown older than 4 years old) but I wasn't happy with what I did.
A drawing of Teen Caillou and some of his friends as teenagers (Jeffery, Jason, Leo, Clementine, and Emma.)
Another attempt at drawing Caillou as a teenager (full frontal view). I think this is more in my own style than the more regular styles.
Another drawing of Teen Caillou. I like this one better than some of my other pictures, so far.
Teen Caillou giving a thumbs up.
Teen Caillou posing on a Canadian railroad crossing signal. I plan to make more like this.
Caillou crossover fanart (so far most of this is a crossover with Harry from Harry and His Bucket Full of Dinosaurs.)
Caillou with Harry from "Harry and His Bucketful of Dinosaurs."
Caillou and Harry talking to each other. Note, there's an error in this picture. I have Caillou saying "Older" when I should have had him say "younger." My bad!
Caillou and Harry walking and talking.
Caillou and Harry posing on skateboards like Bart Simpson (requested by Blakeynow.)
Caillou with Wallabee Beatles a.k.a. "Numbuh 4" from Codename Kids Next Door, Stanley Staines from Stains Down Drains," and Harry.
Caillou (on the far right) with Harry, Stanley Griff, Stanley Staines, Wallabee Beatles, Nigel Uno, and Ned Flemkin.
Caillou in The Loud House style.
Caillou with Lincoln Loud, in both Caillou style and The Loud House style!
Caillou with Lisa Loud, in both Loud House style and Caillou style.
Caillou holding a Thomas the tank engine toy. I don't know if this counts as a crossover. Requested artwork but not requested from me.
Miscellaneous
Caillou as a rabbit (an anthropomorphic rabbit,) one of my most favorite animals.
My "I LIKE CAILLOU" stamp made for Deviant Art. For use by fans of Caillou.
Caillou stamp without text. (Free to use but please keep it positive!)
