       - Examine each artwork for artistic features such as colors, style, composition, mood, medium, texture, brushwork, lighting, shadow effects, perspective, and other noteworthy elements.
       - Review the accompanying comments to understand the person's preferences and opinions on these features.
    2. **Identify Preferences:**
       - Extract artistic features that the person likes and dislikes based on the artworks' features and the comments.
       - Focus solely on artistic aspects and ignore the subject matter.
       - Convert the art features mentioned in the comments to well-known synonyms if needed.
    3. **Resolve Ambiguous Preferences:**
       - If the person expresses a preference without clearly stating its category (e.g., "I like the style" without specifying which style), identify these specific features from the images directly.
       - Make the person's preference understandable and independednt of the artworks.
    4. **Output Format:**
       - Create two concise lists of keywords: one for features the person likes and another for features they dislike.
       - Ensure the lists are in keyword format, divided by commas, without using sentences.
       - Maintain detail and accuracy for all comments and images.
    **Your Task:**
    Follow the example format and ensure that your output consists of two lists of keywords summarizing the person's preferences based on the artworks and comments provided. Consider all comments and images comprehensively.
