The butterfly wings really gives this series its own visual signature. I mean, you combined succubae and butterflies. I've never seen that before. That alone ought to draw in the curious. Then all the other world-building you did (arcubi, etc.), which any reader will be able to get from issue 1, tells us this is going to be an original, interesting story. All the stars are aligning. I have really high hopes for this series.
