Hi! Yeah Uncomfortable highly recommends you use printing paper (A4 8.5"x11"): https://drawabox.com/lesson/0/4/paper. I'd following his recommendation if I were you before continuing, plus I can imagine how annoying it is to draw on paper that isn't flat on the desk.

Anyway congratz on completing your first challenge at Drawabox, which proves that you have determination and strive for excellence! I applaud you. Now, let's see how you did shall we?

Things you did well on:

• Extensions lines are extending in the right directions. Check!

• All your lines have a confident, straight flow. Nice job at maintaining these lesson 1 fundamentals.

• Although not perfect (no one can be perfect at freehanding boxes), you understood that your lines needed to converge. I'm just gonna reiterate that ideally, your lines should converge into one point.

• Fantastic work on varying the orientation of your boxes. Experimentation is so important, so please continue to nurture this skill!

• Your back corners look pretty decent!

• And nice work for doing the optional cross hatching.

Things you can improve on:

• Line weight. For some reason, a lot of your lines are randomly faint, such as your cross hatching lines. This could indicate to me that you are drawing with your pen pretty tilted. Try and reflect to see why a lot of your lines are faint, and if it is because you hold your pen tilted, start holding it more upwards next time. And sometimes I see the lines that are instructed to have added subtle line weight look like they have been skipped entirely. Please draw your line weight with more care and consistency next time.

• Again, no one can be perfect trying to freehand boxes. But a way to improve is by them is to start thinking about the relationships between lines instead of just thinking about the lines in pairs. When drawing the lines of the boxes, you should keep in mind all the other lines in the set, comparing their angles and making a guess based on them. This diagram explain this more clearly: https://i.imgur.com/8PqQLE0.png. 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. (These sentences are from the critique guide I am using, not my own words)

All in all, good job at following the instructions of this challenge to the best of your current ability. It's not about executing everything perfectly; it's about understanding what to aim for in your future practices. And I feel you do.

Before you move on to lesson 2, please trying getting printing paper before continuing this course.
