I think everything in your comic is improving as you've gone along. Your artwork is tightening and improving, your paneling and your lettering! You've come a long way already, so you should give yourself some credit, it's okay to be proud of all you've done so far!
For specifics, I do like how you've done the lettering- using a different color for each character? I think Chp. 1 - Blob Issues ( 61 - 64) has the strongest lettering of all- nice round bubbles and very clear the order of conversation. On some pages the lettering bubbles are really squiggly or wavy, which I think can be distracting, especially when you want to enjoy and look at the details in the artwork. Sometimes the panels are busy or full of lettering which obscures the actions in the panel- so watch out for that going forward, and try to plan ahead
Your paneling keeps improving too! The only thing I would point out is what you did on Chp. 1 - Blob Issues ( 21 - 32 ), the arrows that point to which panel comes next? If you find yourself needing to do this, I would say to rework the paneling instead of adding instructions. You don't want people to look at the paneling and be drawn out of the action and story! Some of your paneling is very simple, like the bottom half of these same panels, where it's just a grid layout. I think that looks just fine for your comic too, and gives it a lighthearted or classic comic-stripe vibe.
The only thing keeping your comic back, to me, is the banter. I totally understand wanting your characters to chat and come alive on the page, but it needs to serve your story and move things forward. It feels like they've been stuck in the same situation for a while here, because they keep talking about what is going on rather than acting on it. Do you write scripts for your comic first? I don't see anything wrong with adding lots of dialogue, if it's something you enjoy, just be sure things are also moving forward.
I liked a lot when the bird was licking the witch to cheer them up- to me it was a cute/interesting thing to happen, and also showed character! I'm also intrigued about the main robot and what their role will be. I really enjoy physical comedy and crazy situations, so I totally empathize with your enjoyment in drawing it- just be sure you don't lose the forest for the trees in these types of situations. Make sure what you put down always serves the story and tells the audience more. To me, having a script and people's eyes on it (without descriptions of what WILL come in the future- have people who read it who only know what is on the page), is really helpful in being sure about this.
Above all, be confident in yourself! You've done a ton of hard work, and that is nothing to scoff at. The more you do the more you'll improve, I can already see it! Keep up the great work and all the best to you! ^-^
