Completed the new version of page 4, with a more dramatic angle to the roof, and a bigger moon for more “presence” (the page, and the story, are about the moon, not the building, after all).   I used acrylic paint for the building and the moon, conte crayon for the clouds, and India ink for the sky.  Here it is, the raw scan above, and with photoshop touchups below:

In Photoshop I darkened the black of the sky, then added more contrast in the roof, and lightened up the craters in the moon a bit.  It ended up looking like this:

Here, by the way (below), is the earlier version of the page, for compare and contrast. An improvement, I’m pretty sure (though I kind of like the big cloud in the older version better than in the new.  Oh well.)
