ill be real: making a living off webcomics is a slow and precarious grind. youre looking at years without profit. this doesnt mean its not doable or that you shouldnt try - you should absolutely try - but be realistic about what you're getting yourself into.
This 100%; though if you've already got a decent youtube/instagram following, that can help you get a headstart on that grind - I'd wager most of the comics who get hundreds-thousands of readers at the get-go probably had this going for them.
I know if I personally see an artist I already follow posting concept art and snippets from their comic process, I'll often go check out their comic.
If I had to rate your art quality @Das.Yaz , I'd say it's definitely good enough for creating a comic, but not good enough to be the main draw for reading it. It looks like you're going for more of a humor/relatable fluff comic, which usually has a even lower threshold for artistic requirements; they usually get popular based of of writing quality + consistency of updates. But it can't hurt to polish your art to the best it can be, so:
This is going to sound weird, but my main critique for the art you posted is that the dog isn't cute enough. The face is good, but something seems off with the pose/legs; maybe it doesn't look natural enough?
slice-of-life/fluff comics usually rely on some combo of: humor, relatability, inspirationalness, and softness - I don't know how to describe this, but basically how you look at a fluffy dog and it's like your scarred heart is healed? that feeling.
Looking at other similar skit comics to see how they handle making things cute/likable, and try to apply that to your own style.
