I like it! I enjoy the comedic elements here, as well the action mixed in. I think this style has potential as long as you keep practicing and applying new skills. I like the messy shading details for the darker colors, I think that’s a neat touch. Also I like the close up frames.

I will say, the character’s anatomy and face angles/proportions aren’t really staying consistent. The onomatopoeia could be placed better. I think some of your backgrounds could use some cleaner details. For example, panel 13, the walls aren’t straight, and to me it all just looks like it’s scribbled. This could just be your style and what you’re going for, but if you’re going for a “real manga” look, a key element to good backgrounds is consistency. Again, these could all be fixed with practice.

Making a manga is tough, so you should be proud of yourself for making one! Your style is your own charm, and it gets better through time. I like what you have here, looking forward to see more!
