First of all, good job on making this! Keep it up, it takes a lot of effort and hard work to keep going and I applaud you for that!
Regarding what other people are saying about the art and it being hard to read... I think the issue with it is not how you draw the characters, but rather, the thickness of your strokes and how you do you crosshatching.
Compared to what you had in your first chapter, I can see you already improved a bit by giving your characters a thick outline. I think that's a good decision, it makes the characters stand out. However, even in your recent chapters, your hatching still has the issue of taking the thunder away from your actual important lines. What I mean is, your hatching often feels random half of the time, and are there just to "fill space". They are also as thick as some important lines, which means that often, I can't tell them apart.
Take this panel for example:
the people on the right initially just looked like a bunch of vertical lines to me. This is because the lines all look almost equally thick, and you use the same thickness on other important parts as well (MC on the left). It ends up being random lines that makes a picture hard to read. For other series, I can tell with a single glance on a panel what's going on, because I can see which lines are supposed to be important and which ones not. But for yours, I have to stop for 2, 3 seconds just to figure out which lines are important and which ones are just random hatching, just so I can figure out what the heck is going on in the drawing.
If you wish to go for a style as complex as Berserk, you'll notice the hatching isn't random, but rather, they often carefully placed in a way that enhances composition/movement. The hatching of each section is also often done differently so the eyes can tell they're two distinct object. Yours often don't have that distinction, which ends up making it hard to read:
If you want to go for a more simple style, I really recommend to reduce the amount of hatching you have and consider using much thinner lines. More isn't always better; it's preferable to just prioritize important details. Composition is very important even in comic, when you over detail part of the piece that's not important, it actually steals away the viewer's attention away from the things they actually want to care about. If you're going with a style like One piece, you'll notice the author uses things like an "white border" around the main subject of the panel to distinguish the important stuff from the background. It also has pure black panels, which makes it visually more easier to read than if it was just extremely roughly hatched.
Overall, I just recommend more visibility and distinction between the important elements of the panels and those that are not. There's many different ways to do this so it's worth doing your own research in it.
Anyway, I still want to say, kudos to you for the comic! Apart from the overall messy lines, I think your artstyle itself is quite nice. Keep it up and good luck!
