Yeah, close ups are awesome.
TIPS: Try to very your perspectives a bit, this is all very standard, med-shot, 2-point, "flat" almost... which does not do credit to those amazing backgrounds. I realize this takes a bit more time, but try to get some more variation in the panels. Make them more... I don't know... dynamic? Every picture has to tell a thousand words.
As for the gore--- it wasn't too gory. *sad face* I found the blood and stuff to be slightly unrealistic as its being spurted out of your victims here... I would have liked to see more realistic damage. (But not waaay over the top, if you get what I'm saying)
Also... you're British? Those miner guys say "old bean." I have zero people I know who say that. heh heh. *Laughs at the accent since I am an offensice American*
...Can I just say that was really weird though? (Especially the tail in the butt part... what WAS that? o_O )
