It is critique time :)

Alight, so let's start with super imposed lines. The straight line don't look half bad but some have a but of fraying on both ends. Using a dot as starting point can work to fox it. I can understand how difficult curves are (absolute nightmare those can be but you keep pushing!)

Your ghosting line are confident i see that, thats great! But they do tend to arch one way on the longer ones. Consciously going in the opposite direction against what you do automatically would work in getting them straighter.

Sadly can't say anything about ghosted planes as those seem to be missing. If you do those and show them it will be alright.

Moving on to tables of ellipses, they overall look pretty good. Hiccups here and there but the majority fits in nice and snuggly. If you keep moving on through the lessons and add them to warm-up those without a doubt become tighter and tighter.

The tables of ellipses you did look solid for the most part and i see that the ghosted lines have improved compared to the ghosted lines. Do keep in mind that when ghosting the ellipse that you do it slow at first to a good speed that isn't too slow or fast and make sure it touches the top, bottom and sides.

First major roadblock is here at the funnels and i can't blame you, they're not easy. Be careful when done the curves that each side has the same distance and not that one is longer than the other resulting in an off center minor axis. The bottom right is what you shouldn't do when it comes to the minor axis and the bottom left you did it perfect!. Now onto the ellipses themselves. When the minor axis is in the middle and you are ghosting the first ellipse, try to stay aligned to the major axis (the line that goes from top to bottom of the ellipse.) Make sure your ellipses gradually get wider as they stray away from the middle ellipse. If you are not sure you are ghosting correctly so it aligns with the minor axis you can turn while ghosting until you get a feeling it is right.

Now time for the boxes.

Not much to say with plotted perspective, they look pretty dang good!

Rough perspective not so much but when not used to boxes, it feels like a mini boss. As long as you ghost from a corner of the box to the VP you should get better over time. You did do some lines over here and all i can say is to stay away from that unless it's ment for line weight.

And here's what i think is the big meanie of lesson 1, rotated boxes.

Some of the boxes look like they have the same VP. To make VP more dramatic make the VP closer to the box. There are some inconsistencies with the boxes but that is ok for now and there is no need to worry for that.

Finally, we arrive at organic perspective

You did a pretty solid job with the teenie tiny boxes but you can crank the big ones up to 11. More variety of box shapes could be done too but no need to worry for that here. The boxes you have presented look fine and dandy!

Overall, you did a pretty solid job and stumbled a bit at funnels and perspective which happen to be the extremely hard parts in my opinion.

If you add the few pages of ghosted planes to this and show them you're good to go for the 250 box challenge.

Good luck!
