It’s good, I’d go for a solid 7/10. Also, about the icons, why don’t you have a go at making them using the pen tool if it is available on your software.
I love the design, especially how it matches the current theme of Roblox’s new client.
Feedback:
I think the “See All” button text shouldn’t be underlined.
This one is just optional, but Roblox has a new search design:
Instead of displaying a colored text for “In Game” or “Studio”, I think it would be better to display a ring or outline around their Avatar depending on their activity, and an Icon on the bottom right corner of their avatar for either in-game, website, or studio.
The buttons at the top and on the sidebar look a bit cluttered and basically all over the place making it look complicated. Maybe move the buttons all into the sidebar?
