Hey there montseag, good job on completing lesson 1. I'll be going over your work today so let's get started.

Starting with your super imposed lines you did a good job staying confident and using your shoulder to drive the motion of the lines. Your accuracy will improve with time but it's a good start. Your ghosted lines are also looking confident, but there are some times where the end of the line has some squiggles due to you trying to stop on the point. Instead of trying to stop, what I do is lift the pen up and not fight the motion. This has the added bonus of giving your lines an aesthetically pleasing taper.

With your ellipses, you have appeared to forget to attach your tables of ellipses, so I will go over your ellipses when you get those to me.

Your rough perspective boxes are hit or miss. The hits are when you pay close attention to make sure your horizontal lines are parallel to the horizon and verticals are perpendicular. On the flipside, there are other boxes where you don't pay as close attention to this and you end up with skewed/distorted boxes. Overall, your lines are showing some serious arcing meaning you might be neglecting using your shoulder. Remember to always ghost and always use your shoulder to confidently execute your lines. Your converging lines are where we expect them to be as indicated by your correctly applied check lines, and the accuracy of those types of lines with a distant target will improve with practice.

Moving on to your rotated boxes you did a good job pushing to completion. The only goal here is for students to complete it so they can learn of new types of spatial problems and ways to go about solving them. Your lines are still a little hesitant here and drawn with the wrist and elbow instead of your shoulder. So in terms of execution you were not rotating your boxes so much as skewing them so give this gif some more attention now that you have context and study how the rotation is driven by the motion of the vanishing points. You did an ok job keeping your boxes packed tightly to leverage adjacent lines as perspective guides. Overall you have a fine start here and pushed through in the face of complexity. Your line work could be a little more confident and some clarifying techniques such as hatching could be employed, but this is a rediculously difficult challenge the first time so good job on pushing through.

Now let's look at your organic perspective. Your compositions have a lot of motion and you did a good job making the forms appear to exist in the same space through overlapping them. Your sense of perspective still is pretty young and you have a lot of divergence where near planes are smaller than far planes, but that will get taken care of in the next steps. You have a good start in making the piece feel three dimensional, and you could have pushed the illusion further with more smaller boxes to appear they are really receding into the background.
