Project Valves: Icon Set

Hey guys, so I'm making my portfolio for graduate studies in UX.
I got no design background so I'm making all sorta projects on my own. My favorite is the Steam Mobile App design overhaul "Project Valves".
This is its icon set. I'm new to dribbble scene so still getting used to regularly posting stuff.

P.S.: I have a lot of stuff I made on iPad Procreate. It's not wrong to post that here, is it?
