Yes, I also hype Houseki no Kuni hahaha
For me Phos was "female" in the beginning and after the changes more "male". I don't want to spoiler to much;;
It's a CGI-anime but the CGI is really acceptable and good! You should definitely watch it by chance!
I tried to color her in anime style with one shadow and highlight per color and not so many color gradients. Also the lineart is all black and was made with a vector tool. o/From today I start my Houseki no Kuni fanart series!
So stay tuned for more hehe
