Congrats! It's such a great feeling, isn't it? Finishing that first chapter can be a daunting task when you're just getting started.
When I finished the first chapter of my comic, it didn't sink in initially D: I spent 1-2 months doing all 34 pages of the chapter, rather than publishing pages as I finished them. So I'd do all the layouts, then all the pencils, inks, tones, etc in stages. So when it came time to put the finishing touches on everything and send it to be printed, it was hard to know when to stop tweaking things.
Now I'm drawing chapter 2 weekly instead of all in advance (cause boy am I good at eating up my buffer :u) so it'll probably feel more complete once I wrap up on the chapter.
