Hello, I see your work and I see the effort you put.

The confidence is there so that's a good point.

The accuracy on the other hand is missing in some points in particular in the ellipses, especially in the table of ellipses.

I'm sorry to say but I think you don't understood the task there (table of ellipses)... In little sections there're too much variances of ellipses and in the sections where's the curved line you use ellipses as borders not only on the sides... You need to have at least two sides of the ellipses that touches a solid line (in this case the sides of the section/rectangle)...

So that exercise has to be redone after rewatching and rereading the instructions.

The only one more thing I have to say is more a suggestion than a critic, 'cause it's well done, on the organic perspective: try not to correct the lines with further lines. The felt-tip pen is there to make you see the mistakes and so to know where to do better.

In conclusion overall it's a great job. Follow the step I write and after that you can move on onto the next lesson.

Keep the good work and have fun. :)
