Those look pretty good! I like how you took the time to make collars for all the robe styles.
If I might make a suggestion. You may want to consider "fixing" the padawan robe style so that the outer layer more accuarately lays over the collar. I'd show screens, but I lost them when PCGM accidentally wiped out all the comments.
Feel free to use my robe template (also on PCGM) as a point of reference (if you're so inclined).
Nice work, once again
