I find the business model interesting. It is difficult to make a living as a content creator. Setting a limited number of subscribers on an exclusive illustration series will probably work better than giving illustrations away for free and then hope someone will hire you. Setting a quarterly subscription of $57 will give the designer $5700 a month if he manage to get 300 subscribers. I am sure this model can be duplicated by other independent content creators, and not only illustrators.

When it comes to the art itself I happen to like this artist's pen. That is a matter of taste and opinion of course. However, the business model is generic.
