@braydin-hawlette & @StudioLooong -- if it helps, most of Canada uses ASL. With the exception of Quebec, which has its own sign language, LSQ.
Braden, it's awesome that you strive to show diversity in your illustrations, and including a Deaf character is great!
Going to agree with Taylor -- if you're going to include ASL, you need to make sure that it's accurate. Otherwise, you may end up offending the Deaf or hard of hearing rather than including them.
I'm going to take her challenge one step further and challenge you to consult with a Deaf person or someone who knows Deaf culture to ensure that your graphic novel is respectful and as accurate as possible. It's not just the ASL errors that are an issue. It's how the story is written and how the characters are portrayed that shows a lack of knowledge about sign language etiquette and Deaf culture.
How come the Deaf girl is the only one signing? How does she know what everyone else is saying if they're not signing? Do her friends know sign language? Does she read their lips? If this is something that I noticed and questioned, as someone who is not deaf but who is fluent in ASL, you can be sure that your Deaf and hard-of-hearing readers will notice it immediately and ask the same questions.
Quick Deaf culture lesson: it's considered rude to talk around a Deaf person if you know sign language. That means that if a group of friends contains one Deaf person and all the rest are hearing, if they all know sign language, ALL of their voices should be off and all of them should be signing. So to a Deaf person, the whole exchange of this scene either doesn't make sense because they're wondering how clear communication is happening ... or they think that everyone is rude because they're talking to their Deaf friend instead of signing.
Just an example of what might appear inclusive and neat to someone who doesn't know ASL or isn't aware of the culture, but someone who knows the language and is a part of the culture might feel and react differently. Hence the challenge: consult with an authenticity reader.
Again, props to you for including a Deaf character. It's SUPER hard to try to clearly capture the motion of signing in an illustration! You've given yourself quite a challenge, but you're uber-talented so I'm confident you're up to the task! Looking forward to seeing more awesome things from you!
Part of my writing process is making stuff up to slap on plot holes that others point out.
