Hi Frosty~ Let’s see...

The line section looks good, though I think you could stand to be a little more confident in your arcing superimposed lines. It’s more important for them to be smooth, than it is for them to stick to the guideline. This extends to your ghosted lines/planes, too. Rather than slow down as you approach the end point, to make sure you’re hitting it, or not shooting past it, simply continue on at the same speed. As we always say, confidence > accuracy. P.S. try not to extend a line that stops short. Also, for the planes, I’d recommend placing start/end points for the non-diagonal center lines, too. It’ll solve the placement/perspective problem, and then all you’ll be let with is a simple, ghosted line.

The ellipse section is really nicely done. In the table of ellipses exercise, be careful that all of your ellipses touch all of the available sides of the frame. That is to say, ellipses shouldn’t be floating inside of the frame. Also, in the funnels exercise, I’d recommend using a ruler for the axes, and a plate, or something like that, for the arcing lines. If the axes aren’t straight, or the arcing lines not, at least roughly, symmetrical, the exercise is incorrect by default. Think back to the ghosting method: we do what we can to make things a success before committing to them, then commit.

Finally, solid work on the box section. My #1 recommendation is an extension of the ‘don’t extend a line that stops short’ advice- don’t correct incorrect lines. If you make a mistake, rather than make it stand out more, by putting more ink in that general area, simply leave it as-is, and be more careful about that particular thing next time. In the rough perspective exercise, be careful that all of the lines that don’t head to the VP are either parallel to the horizon or perpendicular to it. This is 1 point perspective, so they have to behave that way. If, according to the points you’ve placed, line doesn’t behave that way, then that line is incorrect, so don’t commit to it- try again. In the rotated boxes exercise, the back faces aren’t as snug as they should be, and they don’t rotated as much as they should either, but it’s a strong showing, nonetheless. Finally, in the organic perspective exercise, the foreshortening of the boxes is a little too extreme, and the decrease in size not as obvious, so be mindful of that.

To answer your question, it’s perfectly fine for the boxes to be random. We’re building up to the whole ‘seeing them in our head, then putting them to paper’ thing, but we won’t be able to do that for a looong time yet, so don’t stress.

Nice job completing this lesson. I’m happy to mark it as complete.
