Hii DOGGYDOG,

Lines

Superimposed lines: your lines are wobble and are not continuous. they should be smooth and confident. u should draw it fast and continuous.

Ghosted lines: i can find some of your lines are start to wobble in middle. Its because u try to stop ur pen before reaching the ending point instead try this, slightly lift your pen before reaching the ending point u may achieve confidence in ur lines

Ghosted planes: ur line are wobble just plan ur edges and apply ur ghosting method here

Ellipse

Ellipse in planes: they are not so smooth and continuous in my experience ellipse takes time when compare to lines so take ur time and u should ghost it before drawing it.

Ellipse in funnel: same they are wobbly and i like that ur center minor axis cuts ur ellipses into two equal two half thats the purpose this exercise. And dont leave space between ur ellipses they should touch each other but should not overlap

Ellipse in tables: as i said before they are wobble and not smooth and continuous

Boxes

Plotted Perspective: they are good

Rough perspective: some of ur vertical lines are not so perpendicular to the horizon but ur parallel lines are perfect they are parallel to ur horizon

Rotated box: the spacing between the back face of the boxes are good i can see u understand the concept and purpore of the exercise dont worry u can a achieve perfect boxes in 250 box challenge

Organic boxes: I like ur oraganic boxes they are great but dont stike out ur mistakes in future exercise and drawings because u r deceiving ur audience by drawing 3d form in 2d sheet if u strike it, it will automatically drag attention toward ur mistakes

All the Best

Cheers,

Jansiva
