From someone who gets bored of making chapter images very quickly, I’m curious: do you, as a reader, care about seeing chapter images at all? Would you rather imagine how characters look yourself?
I think chapter images spice up an otherwise dull page. 🙂 And if the chapter images are as fun and quirky as yours — well, then. Double fun for everyone! 😄 (except maybe you, since you get bored of making them o.o)
