When you're looking for poses as reference, I find looking through vogue and other high fashion sites helps. Anyway, here are the prefered poses for Preston and Space Oddity. Thanks for doing this by the way!

[u]Preston:

High fashion poses are great JoJo poses.

[u]Space Oddity:

Space Oddity is large and it would be floating behind Preston similar to Cream.
