A way into the drawing

  1. Start with the main forms

    Draw a tall cylinder with a shallow oval at the top.

  2. Build the overlaps

    Add the collar and open mouth, then place the detached cup lid beside the flask.

  3. Choose the finishing details

    Clarify the cup opening and add a small gray accent beneath the collar.

A small thing to tryUse matching ellipse angles for the flask top and cup opening.
