look . . . I was willing to put up with Dejah Thoris and the White Apes of mars, because it told a story that hadn't been told on ERBs barsoom before . . . it introduced new locations, and ideas . . .
But . . . Dejah Thoris and the Green Men of Mars . . . is torture porn.
You are showing a classic literary character, being tortured and personally violated . . . for kicks, and the way it is drawn seems to indicate you think we will be aroused by this . . . this is sickening, and horrible. It implies rape (which should only ever be carefully used, and never as "that thing that happens to women"), and is gross and horrid.
This is sickening . . . and damn you, for taking away Dejah Thoris' chance to murder that sick f**king thark on the third preview page . . . you could have redeemed this story by having her systematically murder her torturers and oppressors, but you had to have her be saved . . . like a weak child, which she has never been in any version . . . not even in the white apes of mars.
As well . . . you are diminishing the humanity of the Tharks . . .you should be showing the Tharks growing out of these habits, you could have made this any other horde (Torquas, or Thurd, for example . . . both introduced in public domain books) . . . but making it the Tharks . . . is contrary to Burroughs story . . . and it takes away your chance to explore the universe further by hyper-focusing on this horde of greens.
. . .
All that said . . . my recommendations to salvage this book, make the preview-pages seen . . . a dream-sequence, show her imagining the horrors the greens will inflict upon her, and imagining John Carter coming to rescue her. It is more effective to imply horror, than it is to outright show it . . . second, change these Green Martians affiliation from Thark, to Thurd . . . . Not much is known about Thurd but it is implied they are sort of the boogie-men of the green martians. . . .
The first change is not so simple, but the second one would be rather simple to accomplish (erasing the word thark, and replacing it with Thurd . . . adding a few new lines of dialogue)
So far . . . you are really going in the wrong direction with this book, despite that . . . I am going to buy it, and I will read it, and I will buy the tradepaperback . . . I love dynamite comics, and John Carter . . . but this is going to be a blemish on your John Carter record . . . keep in mind, implied-rape and assassins-centric plots literally DESTROYED Marvels 1980s series . . . you are doing both right now (assassin plot in main Dejah Thoris series, implied rape in this spin-off).
I almost recommend putting Green Men of Mars on hold until the assassin-story in the main Dejah Thoris book goes on hold and you can put some distance between these two archs with some lore-expanding filler. Remember if you are reminding people of GOOD John Carter comics . . .keep it up, but you are reminding me of the BAD comics in the past . . . so slow down a bit . .
and my final recommendation . . . has nothing to do with the story, but when this is released in Tradepaperback form, can you put Vol. 2 on the side instead of 1? since this is more or less a sequal to Dejah Thoris and the White Apes of Mars?
