I usually adjust the lighting to make the Roblox parts shine. You can achieve this by messing around with ClockTime and GeographicLatitude in the Lighting property.
Looking at the 2007 ROBLOX rendering engine helps too.
I think the need to cover every single surface with studs is unnecessary. In my opinion, the placement of these studs surface should be more thoughtfully considered like LEGO pieces.

A common misconception is that old ROBLOX was “blocky,” but that’s not the case. They used cylinders, wedges, sphere and older meshes. The bed furniture picture below is from Homestead 2007 contest.

As for your classic style build, there’s room for improvement. This type of build comes off as too simplistic in my POV, there’s need more depth to it.
As such, I take a look at LEGO builds for inspiration and real life references to fill my lack of imagination. Here’s my attempt. It’s also uncopylocked if you’re interested in checking it out: Somewhere - Roblox
Also, I have never seen those fonts back in the old days. It seems overused.
This what ROBLOX CoreGUI used to look like back in 2010. They used Arial font.
These are my honest criticism, speaking as a Roblox player who joined in 2010 on my other account.
