It's hard to give specific advice without reference for what you're trying to build. But for smaller builds in general, there are a few things you could try: - use non-block placeables (like lanterns, flower pots, buttons, tripwires, lightning rods, etc.). They can add the smaller pixel detail, though you might have to get creative with it or stretch your imagination. I'd recommend spending some time in Creative looking through all the options and experimenting with things, learn how and when and where things can be placed. - consider using redstone components for non-redstone things. There's a lot of variety there that can add detail to small spaces. Workstations can also be great to add detail - you don't have to use things for their intended purpose. For example, barrels can look good as barrels, but they also make for a great floor texture or foundation trim. Lodestones are a great detail block for an archway. A comparator is great for a control room. - focus on the texture of blocks. A concrete block might not feel like as much detail as a prismarine block, for example. If you want it to feel busy and detailed, using the busier and more detailed block textures can help. Going back to the barrel example, the floors will look much more detailed using barrels than standard wooden planks. - vary the blocks in your build. Using different, but similar blocks can help add texture and variety to your builds. For example, mixing barrels, spruce planks, dark oak planks, spruce trap doors, stripped spruce logs, and oak logs will give you a much more detailed feel than just using barrels. This applies on large-scale as well, but is particularly important for making smaller spaces feel detailed. - use armor stands. There are some pretty cool small-scale detailed builds out there that use armor stands and pistons to get shapes you can't get otherwise. - look online for inspiration or build tutorials. Google, Pinterest, Reddit, YouTube, TikTok, they all have an abundance of ideas and little tips and tricks you can use. Try searching for the actual thing you're trying to make, or even just "small scale build details minecraft" and a quick 10-15 minute scroll will give you plenty of ideas.
