For me, there are three comic artist's in particular, who have greatly influenced my drawing style and my storytelling style more so than any others.
Noelle Stevenson: Her work on Nimona has stuck with me for years at this point, for awhile my sketchbooks were dedicated to emulating her style, and I think at one point I even sent her a message on Tumblr asking for advice? Sadly you can't read all of Nimona online anymore, but I would highly recommend getting your hands on a copy of the book, as it's basically a modern classic.
Emily Carroll: Her short horror comics are dripping with atmosphere, the pacing of her stories is a slow eerie crawl, and her use of color practically burrows into your skull. My Minicomic was based on an old dream-journal-comic I did after reading hers, and now that I think about it, her story "His Face All Red", with its down-to-earth drama/horror with subtle supernatural elements was a big influence on my current comic.
And finally, Luke Howard: All of his stories are weird and dream-like, but in a subtle way. Much of his work is based around the relatable anxieties and lives of his characters, contrasted with a surreal surrounding or setup. For example, his comic "Trevor" is about a man who buys a rabbit for his sweetheart on his way home from a vacation, but he gets buried in his cabin by an avalanche. While trapped he writes love letters describing the rabbit, and the conversations he has with it. Conversations.
Luke Howards strange-subtlety is something I try to emulate in my own work (to varying degrees of success...)
Edit: also as far as art styles go, I would say the three I mentioned all have very similar art styles which I think share a "common ancestor" so to speak, with a 20th century cartooning style known as "Ligne Claire" (Clean Line, in french). Most famously associated with TinTin, but it can also be seen in things like Charlie Brown, and other newspaper comics of the time. That said, you get into fuzzy territory when you start speculating about influences and trying to "name" styles, so yeah.
