It might be funny looking back at the situation now, but it's important to remember that not everyone shares the same interests or sense of humor. In the future, consider making a separate folder for your fanart and other images that might not be suited for everyone's viewing. This can prevent any awkward situations or misunderstandings. Communication can also play a significant role; you can explain to your mom that it's a piece of fanart from an anime you enjoy, helping her understand your interests better.
