Good job on getting through the first lesson I'll be checking your homework today.

Lines

You lines are incredibly wobbly, I'm not sure if you misunderstood the ghosting method or simply need more practice, remember that a confident line is more important in draw-a-box than an accurate one, its okay to go slightly beyond your marked dots so long as the line in between is mostly straight

Ellipses

Elipses are alright, remember to use the shoulder and take your time when ghosting the circles, you want to get a fluid motion using your whole arm before drawing them

Boxes

The only exercise I have some concerns with is rough perspective, I can't really tell where your point is on the horizon line, the lines go a little too far and they seem to be all over the place, not really converging on one point, remember to ghost your line all the way to the point on the horizon before marking it down for the box, if you need to, make the dot on the horizon line bigger, that helps with keeping your eyes on track.
