Message:

program.hs:21:18-82: error:
    • Couldn't match expected type ‘Picture -> t’
                  with actual type ‘Picture’
    • The function ‘rotated’ is applied to three arguments,
      but its type ‘Double -> Picture -> Picture’ has only two
      In the expression:
        rotated 2 0 (translated 4 4 (colored brown (solidRectangle 1 4)))
      In an equation for ‘rightBranch’:
          rightBranch
            = rotated 2 0 (translated 4 4 (colored brown (solidRectangle 1 4)))
    • Relevant bindings include
        rightBranch :: t (bound at program.hs:21:4)
