Revival Feathers

How do they work? I also had this drawn a while ago, but only recently did lines and coloring. You don't want to know what happened to the rest of person blue in panel one. The expressions for Skye were easy in this, but I like them. I have two more comics already drawn a while ago before I have to start making new ideas.

Note: I realized that the white space at the bottom was really bad when I uploaded but my attempts to fix that are failing. D:
