Hi Essam, congratulations on completing the 250 box challenge! Quite an achievement, good job on exercising the patience and the determination to get through it. Hope you remembered to apply the 50% rule and that it all went smoothly in terms of your mental and physical energy.

Now, here is what I have to say about yout submission:

First, there is a big, BIG improvement in your line quality. Your lines are more confident, hit the mark with more accuracy, and generally are more consistent. Great job.

I do want you to do a revision of 15 additional boxes with some extras before you move on, and I will explain why.

A couple important things regarding your lines:

First of all, your hatching lines. While they are optional, if you choose to execute them, execute them in the same manner as you do any line during the exercise. Ghost the line, draw the line confidently. Your hatching lines are consistently a step below your lines in terms of wobble and arching, so when hatching - do the usual process. If you are feeling confident, then try hatching only once per line, but do more if you feel like your lines aren't at the best of your current ability (considering how much you have improved your lines since the beginning of the exercise.)

Second, I see that throughout the exercise you are consistently "fixing" the line by drawing over it if it isn't perfect. As mentioned in Lesson 1 - you put your pen on the paper, you draw, and whatever you got is the result of your preparation, and you move on. "Fixing" lines like this will make it harder to analyze what went wrong, while making it more obvious that there were mistakes made. Do your best to move on after drawing a line.

Now, this section is about the exercise itself, as manyof the given instructions were not fulfilled in your submission:

First, Extending Lines : Up until the last 50 boxes, you have either not extended the boxes to all sides, or you have extended in the wrong direction that faces the viewer. The most recent examples of those are boxes number 199, 200 and 202.

It seems like you have realized that, you have started adding more hatching lines to understand which side is facing you and which sides are facing away, and you have fixed that mistake. However, since you have spent the majority of the exercise making this mistake, it contributes to my opinion that a revision would be useful.

Second, line weight. Line weight may seem optional (even though neither the video nor the text format mention it as such), but it is an important tool to learn especially when moving onto Lesson 2. Please review the last 5 minutes of the video AND the "Line Weight" section of 250 box challenge page and attempt to add them.

Again, congratulations on completing the challenge, I think the revision will be useful to you before moving on, but still take your time to congratulate yourself on completion.
