For the hairstyles, instead of looking at real hairstyles fro kids, I decided to look at some cartoons where the characters are around Canarnyon's age and where they are boys.
This is a short list of the cartoons I looked at:
-Titeuf
-Kid Paddle
-Goofy and Max (Movie 1)
-Cedric
-Martin Matin
-The pirate family
-The Simpsons
