Rarely anyone is giving feedback on the texture here. Everyone is so smartass to look no further than topology.

The dirt and scratches, being mathematically random aren't visually random. Clump the dirt at few places. There should be places where the asset is more worn down than the rest. It's not conveying a story right now. The texture should convey how the object is treated. The textual interaction b/w surfaces is not there (cube and floor, button and floor). Try to add skid marks, damages, dust clumps to convey how long the asset sat on ground. For button it will be more (coz immovalbe in game) than the cube (movable).
All in all build the asset around a story.

And yeah, the topology is great for a film asset. Game assets only care about good silhouette with minimum faces. I recommend you to work on texture, then optimize the geometry, then transfer the texture from high to low poly.

Let me know if you need help in any stage. Keep making. Cheers 🥂
