Big step Sumi!
My personal favorite are the (oven?) knobs. A lot of good detail to capture and your quick material indication is almost there!
Just my opinion, but on the first 6 or so pages watch out on how much you vary your lineweight. Specifically on the perfume bottles there’s so much tapering from dark to light all around the product that it’s distracting and makes the product feel disjointed. I know that’s part of Kwan’s sketching style, but I think it leaves your sketches only feeling 80-90% finished and leaves your silhouette undefined.
