I really loved the art overall and the variety in character design.

I do have a few qualms: the fact that there were some call outs/chapter starts? about certain fairies or types of fairies, but then the book would go on about a completely different type without any kind of separation between the two was very confusing. 

I also wish the artist had been a bit more imaginative than "female fairies have two breasts and look naked" (which is especially jarring when a side note states that fairies don't do gender, even though that is contradicted several times). If you want to do sexual dymorphism in species that look more animal- or insect-like, be more creative!
