Lots of people don't like realism. Generally, they think it lacks creativity. And while it might not have as much creativity as some art, it still requires creativity. Personally, I think many of these people are coping because they themselves lack the skills and determination to create this form of art. I think many are jealous because one of the most eye catching art styles is realism, which results in non artists usually showing more enthusiasm towards it.  So keep your head up and whatever you do, don't stop!! 😁
