To start with the good, the story reminds me a lot of the cartoons from my childhood when it comes to the style and color palette which is a nice nostalgia boost. I think it's got some fairly smooth pacing as far as the progression of the story and each chapter has a decent cliffhanger end that makes you want to progress to the next chapter.
The issues for me come from a few spots. First I, personally, am not a big fan of the info dump text at the beginning. It's a bar I'm rarely willing to jump over to progress through the story. Yours is short enough that it seems to be similar to the beginning of Avatar. I think it could be condensed further so it's at most two or three lines.
Second there are quite a few spelling errors and grammar issue with a lack of periods at the ends of sentences. If English is not your first language then it's obviously gonna be a little harder for you to catch those things on your own. When in doubt google or get an english-native speaker for proof reading if you are able. The drunken speech as well didn't really click for me and it took me a moment to realize that's what it was meant to be.
The art feels really rushed. Your current skill is what it is and will improve with time, but in the first art panel where the captain is drinking the hand is holding the bottle backwards. You would not see much but the edges of the finger curled around the bottle not the whole back of the hand. The second episode especially feels very rushed and the characters look quite sloppy. It continues a bit in the third chapter but it feels less rushed than the second.
The panels also feel quite small. I do not do a scrolling comic but I feel like the ones I see use much larger panels. The panels also feel quite empty in the background. Not every one one needs to have maximum detail but you could benefit from better establishing shots, especially since this is a sci-fi story.
Obviously, these are all just my own opinion but I hope they can be of some help to you!
