Hi @angelina andreas, I think you did a good job with this exercise. The objects you've drawn feel quite three dimensional👍 - I would practice drawing boxes and cylinders some more. I'll point out some things to work on, then after you've retried you can tag me (@Jesper Axelsson), and I'll try to take a look. Common issues BOXES - Parallel edges are diverging instead of converging. Aim for a vanishing point (though, it doesn't have to be on the page). To check your work, you could extend the edges you've drawn with a ruler. Extending them only a bit is often enough to notice errors. CYLINDERS - The ellipse sometimes has the wrong shape - The ellipse at the further end of the cylinder is pointy sometimes. - The ellipse at the further end is too narrow sometimes (it should be as open, or more open than the ellipse for the end closer to the viewer.) I would recommend drawing through the forms (lightly) as if the objects were made out of glass; drawing the hidden edges too. This will help you with making sure that the structure is correct. Combined with drawing from imagination, I think I would recommend drawing from observation as well. Study from boxy and cylindrical objects you find at home (a shoe box and a paper roll for example). Or you could draw from a 3D model you find online. You might want to challenge yourself with trying to draw your boxes as cubes. All the edges are the same lenght in a cube, and learning to draw it, means that you'll learn to control proportions in space. As reference you could use a rubick's cube for example. Or a 3D model online. I hope this helps :)
