>>389895956 months is enough time for a marked change, but you'll still want to have some direction with how you level.
You're going to want to prioritize lineart and fluidity; stiffness is the death of interest for most.
I liked these tutorials and redlines by /ic/'s own teal when I was starting out- it gave me a good idea of how to use construction lines and whatnot. You can find a gallery of his stuff on imgur. It's not his anatomy that you'll want to copy, but his poses. Go through artist's twitters(whatever artists you like, specifically, because the color profile of your webcomic is very much a "you" thing) and do color studies- which is to say, copy their images and look at how their palettes work, and maybe figure out your situation with lineart first- good lineart is extremely important to a webcomic. Also, Incase's Alfie comic is a reeeally good display of how an artist learns to optimize their workflow with a webcomic- he changes his style throughout, trying to find a good medium. It's quite helpful.
/ic/ is also quite bitter, but has some quality pointers and tutorials within its depths if you're not a big baby bitch. It'll have some good material for refining your grasp on digital art.
I was there in your shoes, like, only about a year ago, so I felt the need to drop that unsolicited advice. I hope it helps, though- we can always use more interesting art in the world. Good luck!
