Two characteristics that I thought stood out about the Harlan's last week were the tail pattern and the overall near white of the lighter feathering on the body and head. The tail lacked the typical barring and color uniformity that is present in many/most adult RTHAs and the Harlan's pattern was a more smudged black & red & bright white with vertical pattern/streaking. I thought that was quite striking and different. The other thing that stood out to me was the strong dark/white contrast to the face, head/nape and body feathers on the Harlan's as compared to the browner/creamier contrast on your immature bird.
