Lines are p confident in general, though they do have a bit of arching. You can correct this by consciously trying to arch them on the opposite direction.
Ellipses are p confident too. Careful not to overlap them on the table of ellipses (they should only touch) and remember to aim on the funnels for the minor axis to cut the ellipses in even halves.
Boxes are p good in general with the issue you are repeating some lines. No matter how wrong a line is, don't repeat it. On organic perspective, you can add lineweigh to the silhouette of the boxes in the parts that overlap, but only with a single superimposed line, keep lineweight subtle. Boxes have perspective issues but they'll get better on the box challenge, no worries!
Next Steps:
Don't repeat lines and go on to the box challenge, good luck and keep it up!
