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.
