Other than using the Tapastic forums maybe find a different fitting forum for the topic of your comic and present it there.
Just a quick example: you have unicorns in your comic, then it could go into fantasy forums.
Think outside the box for finding new readers. 
It may be a good idea to initially draw more episodes than you need for your upload, so you have a buffer later on in case you get sick etc. It also helps catching breath when you need a break.
Good luck!
