Many people, I included, consider my writing style on the wordier and more "poetic" side. I tend to focus on my characters' thoughts and emotions more than anything else - for that, I love using metaphors or go in great detail to sort of welcome the reader into a character's mind.
Developing my writing style was a very exhausting journey filled with self-doubt and insecurities. I always thought there was a certain way I was supposed to write my books in and I constantly compared myself with other people. What I was going for was a "casual" writing style as mine usually tended to be rather wordy, etc. and I thought: "Damn, I wish I could convey all that in a more compact and casual way like other people."
It took me incredibly long to realize I should concentrate on what I wanted to write - my attempts at writing in a more casual way were pathetic, to say the least, and I dug my own grave aka I fell into the pit of writer's block because of the pressure I willingly exposed myself to.
So, I wrote. A lot. Without thinking of what would be the best way to write certain things in - I just let the words flow, letting them free to do anything or nothing. Not forcing it is probably the best advice I can give to anyone. And reading. Do a lot of reading. (Though I can't tell you which authors influenced me or anything.)
The only source of inspiration and influence I can think of is my own experience with certain feelings and thoughts. It's because I know what it feels like to be in a certain situation that I can describe my characters' emotions in great detail without even having to think about it. It just so happens that I choose to convey all that in form of metaphors. Because I love them. And that way I can see my writing as beautiful, even though it's not the best.
