I get this entirely, I've stopped writing my blog now because of lack of feedback. Appreciation is the fuel to keep going with storytelling I think, you pour a part of yourself into writing (and artwork to go with it) so that the world can see it, and if you don't get the love back for your efforts then you're just running on empty and it gets really hard. It happened with Superdestroyer as well, which was a really slick webcomic but stopped as soon as it got started because the artist lost motivation, and I was hell of sad because I only found it a couple of years after that had happened. It was so promising but now you can't even read it anymore, it's been taken down.
It's hard to know what to say to you because I haven't been able to overcome this shit in the past myself. I can tentatively suggest:
-Seeking more exposure. Find another cool forum, make an account and make a thread for ZW. Get a new rush of readers, fresh blood into the fanbase.
-Cut to the chase. There must be future scenes you've imagined lots of times that you've looked forward to as high points in the storyline - action scenes, do or die moments, whatever it might be. You shouldn't be afraid to shift them so they happen sooner, or cut the A to B pages of the comic where they're walking around/getting to the next intense part. Once they've accomplished something, make the transition to the next day or next week.
-Love interest. This is a great hook to get readers coming back/discussing your work, and it might motivate you in itself, get you eager to draw/write more and develop your characters. This segues into my next one pretty well..
-Introduce new character/s or element/s. At this point, you have a pretty large body of work. You only have to look at your archive to see that. You shouldn't worry about rushing things, you've gotten pretty far so it would be reasonable to throw another character into the fray at any time.
-Chapter-jumping. This one is great for beating inertia or even writer's block that you can get easily with a single-arc storyline like you're doing. For each chapter, or each event, or however you choose to format it, switch to a different character. You're doing it in small scale at the moment, switching from Stale to Det. You could think of them as one party, though. You could (for example) switch to what Zeke is doing currently, or what Drew is doing currently. Everything doesn't have to be seen from the "main" character's point of view. If you look at George R. R. Martin (Just using him as an example because everyone is into him now), he uses eight or more parties simultaneously, which allows him to write thousands of pages of the same story without necessarily covering a large passage of time or rushing through his story's focal points.
-Sensationalism. There hasn't really been a point where your characters have been in real danger, aside from Stale initially struggling. (Besides which, everyone knows when there's only two characters, no one's going to die yet, no matter what happens.) Put some cliffhangers in, to stir your fans up. Make it appear as though the dog is going to kick the bucket, that'll have them biting their nails. Make them want the next page enough to go and talk about it on the forum or write you a mail.
-Merch. Make use of those few original hardcore fans you have. Design a few Tshirts and put them on a free-to-sell website. The profit is split between you and the site's company, but you don't have to spend anything, print anything, or post anything, you just get your share whenever someone buys your design. Put a link up on your page; if I see you've made $20 after a few days, maybe you'll feel like your comic is worthwhile again.
It would be pretty tragic if you were to abandon your story now. Remember that your fans are all still there, they may just appear dormant. You don't gush every time one of your favorite webcomics updates, right? But you're still following it and enjoying it..
Hope this helps, or at least shows that someone cares about your work, I spent as long thinking about it as I did writing it ;o
thank you so much, yeah I'm not gonna abandon it, just have to get a new view to things and make it exciting for myself again. because if I don't want to do it for myself, why do it at all.
lot's of the sings you have mentioned about what I can do with the plot will happen, but I don't think it's time just yet, even tho I probably can speed things up (which I will now) I still want to pace things properly.
I won't give up just yet
