lol the siiiiiiiiiiink

You've got the right idea! Everything that needs to converge towards the vanishing point or remain parallel is correct. Just watch out for the thickness of certain items, like the windows and the faucet (you can think about the part attaching the nozzle to the wall as just another box, too). Also, it helps to use the paper's edges as a reference for parallel lines, to keep more consistent alignment. For this assignment, I recommend warming up with some line exercises, too: Warmups to Improve Line Quality. Connecting the Dots and Ghosting (practicing the motion of the line by hovering just above the paper before actually executing it) are some habits to also try with this 1 point room.
