body wise, 5 by a lot (petite, huge perfect tits, nice bubble butt), but she never smiles in any of the pictures, so 1/6/7 for a better experience. (amazing gallery overall, thanks!)
This one's incredibly difficult between 1 and 3. I think the particular angle of 1 might give her the edge.
Fits best? 4. But I would go for 2. Edit: looking at one of the later images in the gallery (https://redbust.com/...) I stand by the brunette, just astounding all over.
