I don't do the art myself, so feedback on the general story (flow, uniqueness, did it jeep you interested) would be very helpful!
I'll make sure to give you a proper critique as well as soon as I can.
EDIT: Review time.
So since English is the only language I speak, I (obviously) decided to read the English version.
To start off, the English is a bit rough at times. I'm assuming this is because it's not your native language so I wouldn't sweat it too much. If you're going to continue with the English translations though, it might be worth it to find someone who'd be willing to proofread your work.
Next, I'd highly recommend you change the font of the text since it's fairly difficult to read. I'd suggest something like Wild Words or Manga Temple. They're pretty much the go-to for webcomics. Besides the font itself, the rest of the bubbling is solid. The font size is large enough to read and things are spaced where they should be.
The panelling is also pretty good. One thing I would watch out for are page transitions. Depending on your monitor/screen settings it might not be noticeable (I use 2 monitors but can only see this with one of them), but the panels in the image I linked don't actually blend together smoothly.
For the artwork, the backgrounds look a bit out of place due to the fact that there aren't any shadows. Everything seems very flat because of it and kind of takes me out of the immersion. Backgrounds tend to be a second thought a lot of the time, but I'd say they're just as important as anything else. Just as a comparison, you do have backgrounds with shading and the difference is like night and day (although by the looks of it, are you using external assets for these scenes?). Other than that, there are a few panels where the movement feels "off", but that'll improve as you get better as an artist (I'd like to give more constructive feedback, but as I myself am not an artist I can't really help with that).
In terms of the story, there isn't really much to go off of right now so I can't really give my opinion on it. It starts off with a mystery which may make the reader want to read more to figure out what's going on, but other than that nothing has really been established yet.
