Try submitting your comic to multiple comic groups, if it's on DA.
Also try drawing concept art to pique peoples' attentions. Jumping straight into the comic without whetting viewers' appetites doesn't quite grab their attention immediately, because they know nothing about it.
Also try submitting on multiple social medias to expand your advertising.
If you're new, then the process of gaining viewers will be a little slow, but every step counts.
That's all I can think of :'D Good luck!
