I was thinking you would interpret halos all over the place as whatever you thought looked best, you're the artist here! I guess you could have one halo above my head, glowing of course, then maybe a halo for the logo on my chest, maybe some bands on my arms that look like halos, as well as on my legs or something. Or it could be a little more like Umbreon if you need a frame of reference. Really it's your choice, do what looks best or what you prefer.
