Hi Tree!. I'm chiran. thank you for submitting your 250 box challenge assignment to the community.Today I'm gonna go over your submission. Basically I completed this challenge one week before( you can take me as a newbie) and my observations are mainly based on elodin's guide. i hope I can help you through this and I'll try my best to provide a helpful solid breakdown of your work.

before we get started, these are the name given specifically because of their order and to represent te specific section of the boxes

1. Newbies - ( 1-100 boxes) 2. Intermediates - (101-200 boxes) and 3. pros - ( 201- 250 boxes)

This feedback will consists of three parts. to know more about the these parts, lets dig in!

PART 1: THE PRAISES ( The job you did well)

Your submission reveals that you did take time to read through the lesson materials, followed the instructions and executed to your best of your ability. so that's good job!.

• first thing first, Checking your mistakes: great job! for checking your mistakes by extending the 3 sets of lines away from the viewer. The major improvements can be seen in your intermediates and pros because of checking your mistakes,.

• Lines : How are your lines?- Your lines are smooth confident and are consistent throughout the challenge. It shows that you did take time to plan where your line starts and ends by plotting down the point and ghosting through them and even on hatched lines so thats perfect!

• while line weight and hatching are optional in this challenge, I'm glad to see that you are beginning to build the sense of form ( in this case box) using these tools.I can say that you prioritized confidence over perfection even while drawing those lines.so good job!

• I'm glad that you did take time to construct various types of boxes with different orientation, proportion and foreshortening throughout this challenge without any similar orientation or same type of boxes.

• the convergence of set of parallel lines have much improved in the intermediates and pros boxes

PART 2: WHERE IT WENT SLIGHTLY OFF? ( Where you should keep an eye on) ( No worries!)

Its not at all required to mention here but still, so that your mind will remind you next time to avoid those mistakes. the angle between the Y lines is somewhat less than 90 degree in box 164 and the hatching lines is off in the box 211.

• Starting from the newbies; the boxes ( 14, 30,44, 49 and 96); in these boxes one of the horizontal back corner line was extended a little bit off from the ghosted points and lines. this issue is defenitely reduced in intermediates and pros. but even if you find some points are off , you should still draw those lines towards the plotted points thinking that they are correct. I'm confident that you will definitely improve over time through practice.

• some super imposed lines( line weight) near the end of intermediates tend to wobble a little and they are undershooted also.this effect can also be seen in hatched lines also.

• while you have definitely improved through the challenge,there are times where some of the set of lines converges at a faster rates than the others resulting in converging in pairs. this is point you can definitely work on in your warm ups.

• It's completely and totally normal to have the back corner line slightly off compared to the rest. you should try and work on those next time.

now coming to the part 3

PART 3 : WHAT ARE THE KEYS THING TO REMEMBER IN ORDER TO IMPROVE:

• while constructing boxes using the Y method-the angle between the lines should be somewhat greater than 90 degree to avoid distortion in your boxes. even while hatching your lines, each line should be planned with the ghosting technique before drawing them confidently from your shoulder.

• If you have problems related to controlling your lines where to stop them then Its advisable to lift the pen off the page near reaching the end point. This results in keeping your confident stroke and as you begin to build up muscle memory ,you'll soon learn when to lift your pen in order to stop at your intended point more consistently. If you're already doing this and just need a bit more mileage that's totally fine too, it's all just a matter of figuring out the amount of speed you need to remain confident and when to lift.

• one thing to mention here: relating to the rule of perspective; All the parallel line in the 3d world will appear to converge to a specific VP. so what we can say that our parallel lines should always converge as a set not in pairs and they will never diverge from the VP as this will broke the rule of perspective.

• THE INNER CORNER PARADOX: In this challenge, we are estimating where our lines going to converge to a point. as we are humans, it is almost impossible to perfectly estimate where our lines will going to converge thereby resulting in an error. this error will continue to accumulate as we construct the box freely rotated in space. finally this accumulated error will be thrown to the back corner. So its pretty normal to have the inner back corner come out pretty off.

• I want to take a look at this info here; https://i.imgur.com/8PqQLE0.png

• In this image we can know that how each line will behave relating to the position from its neighbouring edges and the VP.So we can arrive at the conclusion that, If the distance between the internal edges and external edges gets reduce more and more they will eventually become parallel to one and another. Alternatively If the distance between the internal corner and the external grow more and more the internal line will also converge.The diagram can be pretty hard to understand at first, so if you don't understand it, don't get frustrated, keep reading it from time to time while practicing regularly, and it will click eventually.you can also try and start from the back corner if the box is narrower.https://imgur.com/a/DHlA3Jh

MY POINT OF VIEW: from observing your work, you have improved a ton throughout this challenge and there is still room for improvement.I'm confident that your spatial reasoning had much improved now. feel free to add 2- 3 boxes into your warm up routine. through practice they will get better and better and also try to mention your conscious mind to always draw from the shoulder with confidence and to use ghosting method to draw those lines.

Yes, We've come to the end of this feedback. This was a solid submission. I will definitely mark this challenge as complete.

Even though this challenge was hard, you have put a lot of effort, focus and time to finish it so hats off for that.

Awesome! You have completed this challenge. congratulations!. I hope this feedback helps . Have a wonderful journey!

Thank you.
