"he was only 10 years old and already had "cut" abs and a furry snow white chest"
This depiction of him was before age 16 and he'd still kept most of his natural features.
There are a lot of stuff that is implied within the story. The stripes on his nose were just something I didn't really elaborate on. I just improvised when giving my description to the artist, stating as much de-tail as possible. I didn't describe some things for reasons such as this. The more room left for details, the more freedom and creativity can be inserted into a story come writer's block.
