Thank you for sharing !
I would love to help setting up a design from scratch for your novel but this is not the type of sketch I do here...
For this type of drawing it's a full work of character designer ! (I love character design but if I do it I would be a real pain in the ***, panicking, asking too much questions and details, and I guess I would ask payment I'm not ready for this)
I am sorry to reject your request but I won't do it
Thank you for asking me though !
