I probably have a whole lot, but the one I acknowledge freely is that I like taking things slowly, to the point where stories can drag at times.
I think I may this problem too; I think the thing about this is that it's so different on a webcomic site than an actual comic. The story I'm going for isn't a short one, but I can easily dedicate well over 10 pages to a single conversation or scene, and 15 is the norm in some cases.
I've been reading your comic too, and I've been reading it in bulk since I just started, and I actually think the pacing is quite good; and if you were to cut it down and I Read in this style (in bulk) it may even seem too fast.
It feels sort of like this mentality where a webcomic has to be faster since the release rate is generally slower; I keep saying to myself that I'm not ready or about to change the pace from what seems natural in my head just to make sure people are jumping out of their seats with each new episode; but I still find myself cutting out pages to try and improve reader engagement.
But it's hard to say for sure, I try to cut down on conversation that isn't necessary and sometimes I have trouble judging whether something is or isn't, and whether something is too expositiony (for lack of a better phrase), and then this leads me to not reveal enough or get confused on ways to reveal what I want to reveal.
I'm similar to @miesmud in that I feel like I'll disappoint a lot of people, constantly worrying about what upsetting things I might be doing or how I might let the readers down! Pshew!
