To be perfectly honest, it's a mixture of King, Orwell and Child that influenced my writing. 

Orwell was partly an overall meta-influence in terms of how I wrote and the strictures in which my writing held to. I still maintain Politics and the English Language (1946), whilst overall being more relevant for essays rather than narrative prose, helped me immensely with peeling away the seemingly challenging nature of writing and delving deep into its guts. 

King is the major influence in terms of how I set up atmosphere. It's that unrefined style combined with haunting, visceral imagery that I try and put into what I write. It's also the weird surreal situations he sets up combined with the in-laid horror that I unconsciously replicate in my prose whenever I have the chance.

Child's penchant for writing out the rhythm of action held true when I began roleplaying and still holds true today. In spite of his failures, he's got a real good way of getting the grit of fisticuffs or a old fashioned melee down that doesn't feel metronomic like other writers.
