Half of the images in the forum threads show up as broken images with the word "Image" next to it, and half of them show up fine. It seems to be random. When I click "view image in a new tab" it works, so I know it's not actually broken.
I think Dyohna has the right idea. Make some comic friends. The thing is about "getting it out there" is that most people, even if they see your comic and do like it, will likely not come back. There's just too much out there on the internet for people to remember every little thing that they like.
Make a start by hanging out a bit more in this forum. Lots of comic-makers to befriend, and you might be able to get some cross-comic projects going. Otherwise, it's just keeping your eyes out for opportunities.
Here's a question. If, in 10 years, you still only have 20 viewers, would you continue to make the comic (and or comics in general)?
If the answer is yes, then keep making the comic. Work on making it the best possible thing that you can produce, and be happy that you stuck to your guns and created a work of art that you're proud of. Not a lot of people do that. You can be happy with the knowledge that you did what you wanted with your life, instead of saying, "I should..."
If the answer is no, then you might just want to stop now and find something else to do with your time. Because there's just no guarantee that people will read your comic. You can post all over twitter, do #challenges, befriend other comic authors, and even shovel out your hard earned money to pay for advertising, and the people may just not come. Maybe your comic just isn't their style. Maybe it's too similar to other comics they already follow. Who knows? But they might not show up. And if the idea of that bothers you, then you might be making a comic for the wrong reasons.
Focusing on viewers pretty much always leads to dissatisfaction. So focus instead on the product itself.
If you're a MST3k fan, and liked Puma Man, then you might like "Some Girls Do."
I found it, searching for some Sydne Rome movies because she's so... weirdly unique, and I ended up falling in love with this movie!
Also, the song at the beginning is amazing, and yet there doesn't seem to be any actual recorded versions of it. ;_;
It's okay if some of your readers have moved on. Some will still be around and excited to see you update again, and you'll also potentially pick up new people. But most importantly, I think that you should follow your inspiration.
I agree that there isn't enough contrast, so the eye doesn't jump to anything at first.
I think if you were to do one thing to improve it, it would be making the character's lines bolder so that they pop out of the background more. Especially the outer lines that separate them from the background.
