Help optimize SQL query for a custom badge extracting number of words and images, and counting days posted in a topic

Fixed on my own:

WITH summary as (

SELECT
  t.id as topic_id,
  t.created_at as created_at,
  t.user_id as user_id,
  COUNT (DISTINCT p.created_at::date) as num_days,
  SUM (p.word_count) as num_words,
  SUM (
    length(raw) * 2
      - length(replace(raw, '![IMG', '1234'))
      - length(replace(raw, '[img]', '1234'))
  ) as num_images
FROM topics t
  LEFT JOIN posts p ON p.topic_id = t.id
WHERE
    t.category_id = 17
    AND t.archived = false
    AND t.closed = false
    AND t.visible = true
    AND p.deleted_at IS NULL
    AND p.user_id = t.user_id
GROUP BY t.id

)

SELECT s.*,
  CURRENT_DATE as granted_at
FROM summary s
WHERE
    num_days >= 10
    AND num_words >= 1000
    AND num_images >= 10
ORDER BY created_at DESC
