There really aren't any reflections on the tiles, they're just two shades of gray...Great design, but needs more work.

There is no reflected light in this image - perhaps rework it and get it looking more realistic so that it can fit in with the theme more.

its a render without any light setup i did it with only a hdri environment. i didn't added any light and multi color lights also for discoball coz the first entry have it so i did different work from it so no one will say that my work have other entry style
btw thanks for comments

good job on background and disc style but need to improve color scheme

GOOD WORK

Looks good
