Hey KAMIYASORA,

here is the critique guide I mentioned before: https://pastebin.com/dYnFt9PQ

Especially in the lines and ellipses sections it looks like your pen was almost dying. Try to use a pen which is full enough to constantly produce one flowing line.

Lines

They are pretty confident in general! Make sure in the Superimposed Lines, that you place your pen carefully at the beginning of each line to avoid Fraying on both ends. And did you draw the first line with a ruler?

On the Ghosted Lines your pen was definitely dying, so keep an eye out for that. Apart from that looks quite good. Nice confidence, Sometimes I see a bit of wobbling and arcing here and there, but rarely.

Ellipses

Here you lacked a bit of confidence. Drawing confident lines is more important than drawing them accurately, so always focus on confidence over accuracy. Rather smooth Ellipses which don't fit the frame as well, than wobbly ones, which fit in better. Make sure that you spend enough time on the ghosting, so that you can avoid any unevenness in your Ellipses.

But these problems already get better in the following exercises (Ellipses in Planes and Funnels). Watch out in the Funnels,that you keep the Ellipses aligned to their minor axis. And to keep their change in degree consistent and ongoing.

Boxes

Plotted Perspective looks good.

In the Rough Perspective your lines are getting a bit wobbly again and less confident. And I saw that you sometimes tried to "fix" a line. Try to avoid that! It will only lead more attention to the mistake itself and make it worse ;). If a line didn't go the way you wanted it to go, just accept it and go with the "wrong" line.

The Rotated Boxes look quite good. In general, I like that you kept the gaps between boxes consistent between each box. In terms of drawing through your boxes, however, you missed quite a bit in the back. Just like the front faces form a half sphere of squares divided by equal gaps, there should be similar half sphere in the back. Take a look at Uncomfortable's example again and you'll see what I mean.

Your Organic perspective looks sometimes a bit rushed. Like you didn't take enough time to always plan and ghost your lines sufficiently. And a lot of line fixing here as mentioned above.

There are a few Perspective issues, but I hope you worked on that in the 250 Box Challenge. Second Page looks already better than the first one in terms of rushing, perspective and line fixing.
