Hi, I'm in a similar situation as you I guess. I started drawing last year. First time I ever did anything serious. And I feel like my art has come a long way since then. My comic is called "Voidchild" (tapastic.com/series/voidchild/) if you wanna check it out (also we seem to be comic-name siblings
).
I also looked at your comic and you're obviously more adept at this than when I started out. What helped motivate me was another more accomplished author/artist who told me that "a good story trumps bad art". Basically he told me to draw my story myself because if I could portray it well the enthusiasm would shine through.
And as long as you think it is fun to draw, develop and share your story. I want subscribers for my stuff obviously but in the end if that's what I get obsesse about I'm not gonna have a good time. I'm enjoying learning to draw and telling my story and to be quite honest it's all about me.
So be egotistical. That will also help you accept any constructive criticism along the way which in turn will help make your stuff better. If you do it for yourself. That's how I see it.
