Hello AQUIETLULL, I'll review your submission .

1) Lines: generally well done, your lines are not wobbly but firm and smooth, however i noticed that your longer lines are less compact and tend to either move a bit upwards or downwards, try to consciously draw in the opposite direction to counter this.

Good job with plotting the lines in the ghosting lines part, however it seems to me that you didn't fully plot every line in the ghosted planes ( I'm referring to the middle lines) with some it seems you did indeed plot them with other not, you should always plot them because they really help with your aim and accuracy ( this will start to matter a lot in the final lessons)

2) Ellipses: your ellipses are okay, you could really improve them by taking things slowly and ghosting them more.

For example: taking a look at your table of ellipses most of your ellipses have a good flow, are not bumpy and are all drawn two or three times.

However looking at the ghosted planes with ellipses, while you do keep a nice flow , they seem to have been drawn too hastily, the first and the second strokes are a bit too further a part from each other showing that you should have kept ghosting for a little while longer.

With the funnels is a mixed bunch, in some you didn't mange to divide the ellipses in equal halves and in others you did, I'd suggest you to practice them a bit.

3) Boxes: Well done, you've done quite well what was required from the lesson (that is drawing through the boxes and applying the correction method in the rough perspective part), still however I see that some of your boxes are still wonky and that many don't reach the vanishing point. To fix this, here again I'd advise you to plot your box ( i quickly drew one for you to follow how to plot it https://imgur.com/a/6br1IX1) basically you need to plot your ghosted/imaginary horizontal lines that aim to the vanishing point, while ghosting them place a dot before you reach the vanishing point, check if the the dot is still in the trajectory of the ghosted line and if it ultimately leads to the vanishing point.

As for the rotated boxes it seems fine, you did manage to rotate the boxes and kept the corners of the boxes quite close to one another, though you shouldn't have drawn hatching lines on the front planes of the boxes, it makes it quite difficult to see through.

As for the organic perspective the objective of the exercise is quite difficult for beginners, so don't worry you'll have plenty of practice with the 250 boxes.

Anyway I think it is more than "passable" as you have said, rather i think you did quite well.

Good job!
