My attempt:
I put two rounded frames on-top of eachother. But it looks a little off in my opinion, or is it just me?
It feels like it goes “out” on the sides.
The coloring is also a little bit off, because you have two entirely different colors, which adds the effect of stacking on top of one another. Maybe make the frame on the bottom much darker, and the frame on top a lighter version of the new bottom color?
