Drawabox newbie here, pretty consistent so far

  1. Super-imposed lines and ghosted lines, these are good, go up he level ladder by pursuing accuracy and then focusing on not overshooting or undershooting them

  2. Ghosted planes, these look very clean, focus some on not overshooting them

  3. Table of ellipses, it got better as it goes and it will get even better in the future too!, don't do pinches in your ellipse and you should be okay

  4. Ellipses on planes, these are good, make those lines tighter as you go on

  5. Ellipses in funnels, these are good, keep it tight and be sure to match their degrees

  6. Plotted perspective, yep it good.

  7. Rough perspective, not bad, suggest ghosting some more from the vp to yout marked point

  8. Rotated boxes, it's fine, some boxes popped out bit too much making it seem like you missed a box, bottom planes seem consisstent which is good

  9. Organic perspective, overall it's okay, but i see some boxes with egdes poking outward too much, just remember your outer lines should eventually converge rather than diverge away, since most of them are from 3rd perspective

Good luck on your journey

and sorry for bad spelling
