Update: added a third version, as suggested by Sharon in the comments.
Madness has struck and I am messing around with cover layouts. Generally, this is a profoundly time-wasting practice, but since I’ve come this far, let me know what you think of these concepts…
The first one is a mockup. It’s an attempt to position elements to suggest the final cover layout, which would have to be completely re-done by someone with actual art/graphics skills. The small scene at the bottom would need to be repainted. It could be either a very similar painterly scene which fades into flat color, or else an entirely graphics sort of scene. The tumbling debris is meant to link the spider to the dissolving castle structure — and of course the color scheme would need to be adjusted to make a better match between the two elements.
If this was to be principally a print book viewed on a shelf, I would go for even smaller title fonts to suggest that “limit of the visible” idea, but it will be viewed almost exclusively online, so… maybe the font is too small?
The second one is even simpler, and I don’t think requires further comment from me except to say that it would be handed off to a graphics artist for final font selection, placement, and rendering. Please let me know what you think!
