Full Moon Rising discussion

Ok my fellow bookies...I'm reading this book and I'm finding a lack in physical description of the characters, with the excepttion of eye color and hair color. How do you picture Riley, Rhoan, Quinn, Jack, and Gautier look like? I need some help any suggestions would be great :)
THANKS!

I see Riley as physically fit, average build.
Rhoan I picture as slender and paler than Riley.
Quinn is tall. Jack I picture as short and stout. I don't know if he has a mustache, but one would definnitely fit him. I can't remember Gautier.

I think the author left most details out so the reader could use their own imagination to fill in the missing characteristics.
