If you look closely, you'll notice the majority of those 55 followers are on a collaboration comic I host under my account made by more than 15 authors.
I've been updating regularly for about 3 weeks, 3 pages a week, changed my comic thumbnail. Still no new followers...
Your first upload is a bit long- you might retain more readers if you broke that into two or three parts.
Honestly, the followers I have now, came from my forum posts, I don't think I'll ever get followers by being on the "fresh" section, once my comic was there for 3 hours and nothing happened 
I do get a lot of views on the comic website though, so people are reading my comic, they just do not interact with it.
I started this comic because I wanted to create a comic on the subject I like and I didn't find anyone else doing it (either pros or amateurs).
Maybe one of the reasons nobody is willing to draw such comics is that each page takes a whole day to produce and the details to draw are endless...
Bleh, guess in the end I'll keep the comic to myself
