Hello! Let me give you some tips.

Lines

Your ghosted lines seemed a bit wobbly. However, I also noticed some improvement with your ghosted planes. Remember not worry about accuracy, as confidence is much more important. Try focusing on the end point as you draw your lines. Drawing from your shoulder helps as well.

Ellipses

Your ellipses in tables are drawn well. Some of them just need to be a little closer to each other, but not too much to overlap. The ellipses on planes should also be a little closer to the boundaries. The minor axis of the funnels need to be in the middle to keep it symmetrical. Some of the ellipses in your funnels have only been drawn once. Remember to draw through your ellipses all the way around 2 to 3 times.

Boxes

The line work for your boxes are also wobbly. As such, the same principles as the line exercises apply here as well. Confidence is key!
