Those are more purely line focus exercise but you can do basic geometric form like cube they are great to pratice line also speiclally if you draw them as if there are see throught.Least intuitive of all those exercise is the grid exercise where you try to draw parallel line and try to make consistent square will doing so this is a good exercise to learn to visually estimate distance.You can also do doddle on the side of page anywhere you go and have free time just to get some extra practice done but also to build your confidence daily.
