What an incredible piece of feedback! Thank you for taking the time to write so many of your thoughts -- it's no exaggeration that this kind of thing makes my whole day. :-D
On the subject of human-djinn babies, canon is canon. But, hey, that's the beauty of fanon, isn't it! ;-) And regarding MC's hair -- it's actually a deep brown, but sometimes the lighting of a scene can make it look green.
Thanks again! This made me giddy to read!
