Hello! Grats on clearing L1! Crits are a lil slow in these days, so here's mine!

Lines: You'd need some more confidence in your lines moving forward. This means that you should try to aim for a smooth, clean line first and foremost, even if this would mean that the line would become inaccurate. Remember to apply the motion of the shoulder for all your lines, as this would ensure the widest range of movement and thus give a straight line more easily. Where your lines are confident, I sometimes see some arcing, telling me that you may be using some of your elbow and/or you're not gripping the pen well enough. Do take note for the future.

Ellipses: Try to note your ghosting: some of your ellipses are a little mishapen. Make your motion smooth and uniform to ensure that the ellipse would come out nicely. And, for that matter, remember to trust your ghosting. This prevents "jagged" edges in your stuff, smoothening the ellipse and making it come out better. Even if this would result in the ellipse leaving the border, just push on. Don't try to correct it, just trust your ghosting in execution. In the funnels, your ellipses are fairly aligned, so that's good. But, I think its once again worth noting the jagged edges thing. In a bid to get your ellipses to fit in the funnel, some of them are really sharp. Try to avoid this.

Boxes: Overall, not bad. As a general note, do try not to correct lines, even if they're incorrect. Doing so would only bring unwanted attention to the correction, which would not be desired. Instead, move on from the error and treat it as though it were correct. In addition, I will comment that box construction isn't perfect, but you'll get familliar with box construction real soon, so not to worry too much about that.

In the rough persepctive exercise, you can make the boxes a little bigger, and, you can have the box be much more spread out. Even if it would mean that the box would be on the other side of the page, that's fine. You don't have to be limited to close to the vp.

Rotated boxes are a little thin, but from what I can see, they're fine. Keep at it!

Organic perspective: I think you've captured the main idea of the exercise, and I'm quite satisfied with the differing sizes of the boxes.

Overall, not a bad job! Keep at it, not forgetting the 50/50 rule. With that, I think you're good to move on.
