CAVEAT: I'm not a user of Patreon, but here's some of the thoughts I've been collecting from studying people I admire/ want to emulate since I've been plotting to start one -- if anyone in here who actually is using Patreon has had a different experience, by all means, CONTRADICT AWAY! 
In order to find your Patreon, I went wandering through your social media until I found a post on Facebook that links to a post you made on Patreon. I later noticed there's a link off to the side on Tapastic, but most of your social media presence links to your Tapastic page and has no "SUPPORT ME ON PATREON! :D" link. And I was LOOKING for it!
Most of the time I end up seeing Patreon links with comic updates ("here's the comic, by the way, remember to check out my patreon!") or in updates on twitter/tumblr/etc. I understand not wanting to be obnoxious about it and I think that's a good goal, but if it's not easy to find people will miss it, and if it seems like you treat the patreon incidentally, like it's just something on the side that's no big deal, then your readers will see it that way too and won't be eager to support you.
I also notice you don't HAVE a lot of social media presence, which might hurt your ability to get patrons. Something I've seen people comment on over and over, and I've experienced myself in just the month I've been here, is that Tapastic readers don't like to leave Tapastic. Plus, I've noticed Tapastic is really geared towards sharing your comic work more than yourself as a creator, while Patreon is sort of the exact opposite -- you are ultimately selling yourself; you produce work for free and ask people to support you because they like you as a creator and want you to succeed. This isn't necessarily saying that you should go sign up for Twitter right now, but that if the only way people know you is from the comic pages you post, you're going to have fewer patrons than if people want to invest in you personally.
I think advertisement can help, but it has to be the right kind of advertisement -- "PLEASE GIVE ME MONEY, LOOK AT MY PATREON PLEASE" over and over again tends not to go over well, while "ahhh thanks so much to my supporters, here's a sneak peek of the patreon wallpaper for next month :'D [CROPPED IMAGE] don't forget you can support me on patreon for a free monthly wallpaper!!" might go better, and if your supporters know your situation from social media, then things like "okay gang, I added a new goal to my patreon [LINK], if I'm able to take fewer hours at my job I'll be able to update the comic twice a week instead of once!!"
It also wouldn't hurt to take a look at people who are doing what you wanna do and getting tips there. Here's some webcomic Patreon pages that I know are doing well off the top of my head:

- For those that have videos, the video is short (under 2 minutes) and explains what you'd be supporting and what you'd get for supporting. This video is a pitch. Michelle's is mostly a pitch for her comic, Der-shing and Tracy both pitch their comics quickly then explain how your patronage will help them personally and what they'll do in return, and Ryan focuses on why patronage will help him (since his projects are more varied).
- There's also a good variety of styles; Der-shing was nervous about making a video and never shows her real face, while Ryan is less artistically inclined and leans on shots of his comic and himself talking. Michelle doesn't talk at all. All three manage to make something really sincere and appealing.
- Speaking of pitches, the text should be a pitch, too. Look how short the text is on all the patreon accounts I've linked, and see what they're focusing on. It's all about (a) what your support will do and (b) what you'll get for supporting. Your art journey is cool, but I don't think it's helping you here! The text description here can certainly be personal, but more in the sense of thanking a friend for thinking of helping you out. "I make a comic called Bite Me, about [blah], I really love doing it and with your support, I'll be able to [blah] / and I need your support in order to [blah], thank you so much!"
- I think your rewards are fine, but it might be worthwhile to look at Patreon accounts that are doing what you want to do successfully and see rewards they offer. You might get some cool ideas!
- do you follow anyone with a Patreon account that's doing well? It might be helpful to do, to see how they advertise and how often they talk about it!
This is a mess and sometimes a misunderstanding that unfortunately, the people running patreons have to work very hard to dispel. In fairness, there's some artists who get a patreon and suddenly shove work that used to be free behind a paywall, and once you've seen that happen it's hard not to have bad feelings about the system. Emphasise to these people that the comic will always be free, and you really appreciate them reading!! Always describe rewards as being a gift to thank those that are supporting you rather than something you're selling. SOME PEOPLE ARE JUST WEIRD ABOUT ARTISTS NEEDING MONEY, though, and that's all you can really do!
OKAY THAT'S ALL I CAN THINK OF, I hope something in this ramble is.....remotely helpful xD
