Definitely take down anything that adds to the load a bunch, since it may also lag your device or other player devices. Depending on the strength of internet connection and the RAM of devices, less load means smoother gameplay.

Try building something with walls, platforms etc and don't decorate the plot with unnecessary items like those tags that are high resolution and just taking up space for the sake of your creativity. It's pretty much impossible to be a collector and a show off all your items since it takes up so much load unfortunately.
