I don't really see much in this one. The animation is simplistic and bland, the mic is bad quality, the background music is also quite annoying. People usually do these slice-of-life story animations without animation, and add flavor to it by adding effects, a large amount of different facial expressions and different scenarios into it. For example, one moment we're staring at your character in an empty space, and then all of a sudden, we find you in some sort of museum. You also need to do a bit more on the video and sound editing.
Your voice is also not very clear. I'm no sound expert, but you really gotta find a better mic or something that helps. Although I don't recommend buying the most expensive ones (yes, they're high quality microphones and all that, but that don't always make them the best), you should do something about it.
Next is that if you want to talk about a story or something, always attempt to prepare a script, so you wouldn't get stuck in between sentences. Many people actually write their script down and then read it while your voice is being recorded. Also, the reason storytellers don't use background audio is because they want their voice to be heard and clear (That's as far as I got when trying to figure out. Cut me some slack, pal).
Lastly, try to get your hands on a nice drawing program, like maybe Adobe Photoshop, Paint Tool SAI, Medibang Paint Pro. Pick your flavour! MSPaint isn't always a good choice to go for when drawing. It's so... Edgy and pixel-ish. If you want to go grab some animating stuff, you can go check Adobe Animate or Adobe Flash CS4-6. It's preferable not to use Adobe Illustrator, though. It is an art tool, yes, but Photoshop is something more for art most of the time. The difference? Illustrator uses vector lines,and Photsoshop uses pixels (Yes, I know I just said that MSPaint has a ton of pixels to it, but these are way more obscure. Sort of. It has resolution to it.)
IN SHORT: Try to edit your videos, fix your audio problems, make a decent script, and try to use some more favorable drawing programs. Paint Tool SAI and Adobe Photoshop CC are effective drawing tools if you have a drawing tablet.
Take these things into consideration when you make your next video. I like your determination, but try to fix these issues, and you'll get better quality videos.
