The thing I immediately notice about this comic is that there are too many tones and they're too heavy.
If you look at manga, you'll generally see that ones that use hatching (like Naruto or Attack on Titan) don't to use a lot of screentones, and when they do, they're rarely very dark or fancy patterns. At most, it's usually things like a flat, fine-dotted tone across a whole character to make them pop into the foreground or fade into the background, and you'll never see multiple patterned or gradient tones in a single panel. Look at how great mangaka use tones sparingly with inking detail and black fills to elegantly create depth and interest and try to emulate their methods.
I'd also advise cutting down all the stuff at the start of every update. We don't need to see your cover and full-page length dedication and everything before reading every time. It will probably put a lot of people off. If you want something, a simple banner with the social media tags will do.
Apart from just generally to continue working hard at the proportions of your figures, which seems to be improving as you go, those are the main areas I see for improvement.
