okay first of all, your set up and hook is really good!!
I really don't like those very western style comics, but you still got my sub for now because I think the story could be worth it
critique would be that the font is a bit big... i'm reading at the desktop rn and there I's a bit awkward and the bubbles eat a lot of the page width
try finding a sweetspot that looks good on mobile AND desktop and it'll improve the readability
the language is good and I think it's cool that you can tell who's talking by the way they talk. some repetitions are in there tho like "we both know" ... might be a stylistic choice, but then it needs to be a bit more utilised as such ... but that's nitpicking
sbout the art... well I can't comment too much on it bc I'm just biased.
maybe a bit more thought into establishing shots would be nice
like for example ones that hint at the town being deserted, or the bar being out of bussiness, but that's not a must either. having it very "face focused" can also work just fine
that's what I can think of from the first two eps, I'm looking forward to him going on his hunt!
