It's really cute, I like your style!

I hate to be a weeaboo (I mean ffs, 네 여자친구가 한국인 사람이야), but even I can't deny the ugly parts of Japan are pretty beautiful. Totally as an aside, if you ever go to Japan, stay away from the major cities like Osaka/Tokyo/etc and instead take the train for 3 hours out of Kyoto for the most beautiful anime-esque scenery

Looks really nice! You've got a good balance between loose but clean. Don't be afraid to tilt those box tops away from the viewer-- Play around with pushing the perspective harder to help the boxes look more settled and natural. IMO they look a little floaty.

If that's a skill that you haven't practiced, try looking up some videos/guides for drawing in perspective, and just practice setting a horizon line and orienting boxes to it. You'll feel your scenes become more grounded and cohesive.

Great job though, it's overall pleasing to look at and a cool style.

First off, the marble background, if that's what you were going for, is phenomenal, the color and texture is spot on.

Your colors are begging for more saturation, rich beautiful saturated colors. With some work on perspective and some shadows to support it the realistic vibe I think you're going for would really work well. Unless that's not what you're going for and you've got a vibe and style you want.

I can see some good wet on wet (like the rust suggestion on the pipe, among others) which I love, and given your couple of months introduction is just great to see, wet on wet has a ton of depth to it. Keep experimenting with it. I can see you playing with shadows, they are so hard, but keep trying. Shadows can do so much heavy lifting in a painting when they are done right. 💛
