Hi Elmrpaco, good job finishing this lesson! I'll be critiquing your work today.

Things that you can improve on are:

Line confidence. By drawing from your shoulder and ghosting your lines, you'll be able to have greater freedom of movement. If you're worried over accuracy (the lines hitting the dots or the ellipses touching the planes / each other), please don't be. The important thing here is for you to establish a confidence in drawing your marks over accuracy. Accuracy will follow eventually as long as you're carefully using the ghosting method. Do not hesitate with your marks, or else it will result in wobbling.

Use ghosting method. This will help you make your ellipses firmer when drawing over them.

Drawing over your line marks. Do not draw over your mistakes even though you want to so bad. This is in line with my comment about confidence in what you've decided put on the page.

Take note of the width and height lines when plotting the rectangles in rough perspective. As we're using 1-point perspective here, remember that only one vanishing point is visible in the scene. Meaning the other two vanishing points will be at infinity, and therefore the lines will be parallel horizontal (width lines) or vertical (height lines). Remember this when plotting rectangles next time you try this exercise out.

Well done on your rotated boxes and line sections.

Just some revisions needed and you're done!
