Oh man... that's a loooooong story! 
I've had many obsessions over the years, and early on when I was a kid, taught myself to draw characters like Mickey Mouse or Simba or Sonic the Hedgehog from memory in the usual styles they were drawn in.
Then I started to experiment with doing my own drawings and developing my own artstyle, particularly inspired by Warhammer artwork from the time, but also by Tetsuya Nomura's artwork from Final Fantasy 7 and 8, and also the trickle of anime starting to appear on UK TV, most notably Digimon and Cardcaptors (a heavily edited version of Cardcaptor Sakura), so my art from my early teens was all over the place:
Yes... yes, those are Warhammer 40,000 Triple Triad cards. I know, that's bizarre.
My OCs from when I was 14... yep.
I kept on drawing in this weird, hybrid kinda style that sometimes leant a bit manga until I was eighteen or so and discovered Naruto and Bleach. It's hard to understate the enormous impact these manga had on me. The way they were distinctly manga, but used things I'd previously thought of as "more western" like hatching, or more realistic anatomy (compared to the cutsier styles I'd been used to) and so they really helped me pull my art style together. By the time I was nineteen, my art looked like this:
(Rekki from Errant has been around AGES, She's an OC I've been making comics with since my teens, even with the sword draw magic still used in Errant!).
I entered and placed in some competitions in the years after this, like the Rising Stars of Manga (UK and Ireland), and Manga Jiman, was just getting into pitching to publishers and then BAM. The 2008 Financial Crisis hit. Nearly every publisher stopped taking submissions and pitches, Tokyopop imploded, and in the next few years, being a manga artist became profoundly unfashionable!
...So I diversified. I learned digital painting and games art skills like 3D modeling, and I also started to make art in a dot-eyed art style that turned out to be popular with tech clients, so I was making a lot of stuff like...
and:
I think my more cartoony work is most heavily influenced by a mixture of Bryan Lee O'Malley and Kiyohiko Azuma, but maybe there are influences there I picked up without really thinking! 
Then... After a long time making work for clients, and drawing other people's characters, I had a yearning to make my own comic, something original, maybe with my characters from my old webcomic, but rebooted into something modern. I was happy to learn that manga had kinda come back in fashion and it wasn't cringe any more, so I could embrace my weebiness as much as I wanted. I was able to bring in some newer influences like I aspire to have the sense of mass of Hiromu Arakawa's work, and my sense of comic timing and more cartoon-like energy is heavily influenced by stuff like Azumanga Daioh, Yotsuba&! and Scott Pilgrim, and the bold colour and lighting owes something to "Enter the Spider-Verse" for sure.
So Errant looks like... this:
