hello! today i'll be critiquing your homework

superimposed lines- these look solid

ghosted lines- your lines are a bit wobbly and don't look very confident upon closer inspection. wobbly lines are generally incorrect- as long as the lines are straight and confident, you're doing it right.

ghosted planes- the lines are a lot more confident here. however i still think some of your lines are arching, and not in the way that's natural for your arm- they look nervous. for reference, look at the planes at the bottom of the first page of the ghosted planes you posted. they wobble and are bumpy. you might need to work on this

tables of ellipses- these look solid overall. some ellipses fall outside the table but that's fine.

ghosted ellipses- some of the ellipses don't touch any borders of the planes. however, this will get better with a little bit more ghosting and practice

funnels- some of the ellipses aren't symmetrical across the minor axis, but overall solid.

plotted perspective- looks solid

rough perspective-this looks solid as well. some of the lines on your boxes have the same problems as ghosted planes and lines. not all boxes reach the vanishing point but it's quite close.

rotated boxes- solid, especially for a beginner

organic perspective- looks fine, although you seemed to struggle with some of the smaller boxes. also there aren't many variations in the angles of your boxes.

Mainly, you need to work on your confidence in ghosting and drawing the line.
