Arrows

1. Mistake on lines: pass

2.Arrows not compressing: pass

3.Lineweight related: pass

Organic Forms

1.Mistakes on lines: pass

2.Not following the simple form they need to be; they should be 2 identical balls connected by a tube of consistent width: some sausages have uneven ends

3.Degrees of the ellipses/contours don't change, they stay static: pass

4.Not hooking contours: pass

5.Misaligned ellipses and not drawing the axis line: pass

6.Ellipses not touching the boundaries, or getting out of them: pass

Texture Analysis

1.Doing dotting or any kind of hatching to achieve transition: pass

2.Not doing a seamless transition on the gradients, if either the black bar on the left or the white bar on the right are really easy to spot because the transition isn't smooth enough: pass

3.All marks on this exercise should be done purposefully, and by looking at the reference before, so scribbling or doing non planned marks is a mistake: pass

Disections

1.Not wrapping the textures around the form: pass

2.Not breaking the silhouette: some of the textures aren't breaking the silhouette

Form Intersections

1.Repetition of lines, lines not being confident, not planing lines, not ghosting, clear divergences, not drawing through ellipses, etc.:

2.The forms need to have consistent foreshortening: pass

Organic intersections

1.Not drawing simple forms. On this exercise the forms should be kept simple, just like in the previous organic forms exercises. 2 identical balls connected by a tube of consistent width: pass

2.Shadows sticking to the forms. The shadows have to follow the form of object they're being casted on, not the form of the object that casts it: pass though there's a bit of confusion on some sausage's cast shadows especially on page 2

3.Not ghosting lines, not hooking the lines, adding linweight by tracing instead of drawing confident lines etc.: pass

4.Not drawing through forms. You should always draw through forms, just like in the form intersections exercise: pass

5.Drawing non stable forms: pass though a nitpick is some of the support is a bit floaty especially the monstrosity that is page 2
