I can't really give any advice for now, your art (style) is really free and I kind like it a lot!!!
The flow works well (but can be since read really fast through it - in a bit of a hurry)
But checked out the other comics and have to say this one can very well be your best (art and story wise!)
You got me to subscribe so that's a plus. As for advertising/promoting just stick with posting since it is relatively new, I think it will gain wore traction the more dedicated you are to it! (Don't let it become like your last comic mentioned above)
Motivation is a fickle thing so if ever you lack inspiration just come ask around for ideas on the forum, watch plenty of youtube videos and google ideas!
Never forget to take time to evaluate what you have and where you are heading, if the plot forward gets hazy go back to what you have and build up from there (a break to cool down is always good - just don't drop what you have unexpectedly)
Those are my only thoughts
