I wouldn't really call Last Resort "ultra-violent".
Definitely violent, but not in an intense, gratuitous, or continuous way.
Build-up, plot and characterization are really the corner stones of your work. The violence is just there to bring out the different aspects of your characters for the reader to see, unless I am completely mis-reading it.
Strangely enough, that's actually more like what I was planning to do, but with a much broader scope, and a slower rate of introducing new characters (seriously, your cast page is tiny compared to your actual cast. How is the new reader supposed to absorb all these identities?). One way or another, your turf is mine.
Granted, I plan on more graphic violence, with a more decompressed art style, particularly around the fight scenes, but Last Resort does have a lot in common with what I was planning to do.
--and yeah, I already read Last Resort because D told me to. It's good stuff.
Edit:Removed a rogue line-break, which crept into the post, unnoticed.
