Mapping Out Illustration Points - Night-Gaunts

Out of what crypt they crawl, I cannot tell,But every night I see the rubbery things,Black, horned, and slender, with membranous wings,They come in legions on the north wind's swell,With obscene clutch that titillates and stings, Snatching me off on monstrous voyagingsTo grey worlds hidden deep in nightmare's well.
Over the jagged peaks of Thok they sweep,Heedless of all the cries I try to make,And down the nether pits to that foul lake,Where the puffed shoggoths splash in doubtful sleep.But ho! If only they would make some sound,Or wear a face where faces should be found!

Before I even think about my final illustrations, I have to consider which points in this poem to actually illustrate - this will also tell me whether or not I'll be able to meet the minimum of ten final pieces without choosing another tale.

A list of the possible lines I could illustrate:
Out of what crypt they crawl, I cannot tell,
They come in legions on the north wind's swell
To grey worlds hidden deep in nightmare's well
Over the jagged peaks of Thok they sweep
Or wear a face where faces should be found

It's interesting to point out that the fact that these creatures do not have faces is mentioned last - perhaps, of all the illustrations, I should dis-include the head only to reveal their facelessness in the final image? From this poem, I feel I could derive a maximum of 5 final illustrations. With both this poem and The Cats of Ulthar short story, I would like to plan a possible 12-13 pieces, just in case I decide later on that one of the images will not work as well.
