I'll start with the positives. The art is great. I like the style and colors.
A lot of my issues are down to personal preference. I appreciate stories that trust the audience and have characters reacting believably to the world around them. So, when I see a person looking at some gross body horror giblet monster, and she assumes it's just an old guy, I get a bad impression. Maybe it's meant to be absurdist, but the art doesn't really inform that notion so I really don't know what you were going for.
I'm not in love with the dialogue. The main character talks too much which wouldn't be a problem if I got the impression what she's saying is important. I didn't. She didn't need to say, "I'm starving!" The tummy rumble would've sufficed. A lot of her dialogue seems super forced, like when she says "I'm so flipping unstoppable!" Again, personal gripe, but the narration could've been cut. There are more engaging ways you could've conveyed her motives (not that I find them interesting but I'll let that slide since this is only the first half of the introduction).
Some of the pages and panels were hard to read. Not in terms of text but in conveyance. It's not always clear what I'm looking at or what action is supposed to be happening. I might just be the wrong audience, but the fan service isn't compelling. It seems you were more concerned with showing the MC's body than developing her personality. There was no purpose to the fan service, it was just there. I found myself asking, "Why are you just showing me her vagina?" Yes, she's a lifeguard, but that's clearly just an excuse to give her a hot design. You made it clear that she's just in it for the money, so her choosing that job specifically isn't indicative of any deeper or nuanced motive.
Anyway, this isn't for me, but I'll keep reading because I feel like I should at least give this story a chance. If for no other reason than I'd like to share my own comic one day, so I'm feeling empathetic. Story, characters, themes, and subtly are more important to me than artwork, hence the score.
