My modern day influences would include Glen Cook, David Gemmell and William Forschten
Fortschen, IIRC, and nice taste.
Authors that have really influenced me... now, this is a fun question. There's more Terry Pratchett in my writing style than I care to think about while sober; fortunately, you people haven't seen me letting 'go' on comedy on this forum yet, but when I do... yeah, you'll wonder if I'm just copying Pratchett passages and changing the words a few times.
What you have seen of me is my dramatic stuff, and there's three authors I can consciously identify as incorporating elements of. Only two of them are scifi, which, for me, is shocking (scifi geeks represent!)
-Robert A. Heinlein. The king of them all. This is where I learned Everything I Ever Wanted To Know About Characterization. Stranger in a Strange Land, IMHO, is one of the biggest books the 20th century will be remembered for as part of the literary canon in time, if just because it's such a wonderful characterization of the outcast.
-Larry Niven. No, his characterization's paper-thin. And yes, sometimes his technicals leave something to be desired. But... this guy can tell a story like nobody else. His imagination's fertile, sure, but that's only part of it. He can take the things he thinks of and spin them into stories that stay in my head for *years*, because he's jsut that good at raw storytelling. If I could figure out precisely how he did it, I'd make money writing instead of as a hobby.
-T.S. Eliot. Specifically, his language. In every poem, the man sets mood with just the word choice. "...like a patient etherized upon a table." You don't have to know the poem to know that the author's referring to something almost dead, something emotionless, and is probably projecting his own feelings of angst and depression onto <whatever>. And that's with seven words. Simply amazing.
