Hello.
First of all, you seem to be asking the wrong question. It's not about "what I can do to become famous" but "what I can do to improve my work".
I looked at your comic and it seems it already has a genre, though I'm not sure how popular it would be - most people are looking for characters they can relate to/inventive stories. Your comic is more of...reminding of the basics?
But I guess, the short answer to your question is: PRACTICE, PRACTICE, PRACTICE! Perfect your art (perspective, anatomy, style), writing (storytelling, scripting, world building) and technique (colouring, lineart, etc). Use social media to promote your work. There is no short cut.
I'd highly recommend you go through those treats too:
