Shading Pencil Techniques
	Needs Improvement 6 pts	Satisfactory 7 pts	Good 8 pts	Excellent 10 pts
Shadows	Needs Improvement 1. difficult to distinguish light source with values. 2. Shadows are not congruent with implied values of light source.	Satisfactory 1. values aren't correct. 2. Shadows are somwhat congruent with the possible light source	Good 1. Most sides have all the correct values. 2. Shadow is somewhat congruent with the implied light source.	Excellent 1. All sides have the correct value, highlight, core shadow, midtones 2. Shadow is congruent with the light source.
Perspective	Needs Improvement 1. lines are not aiming towards any vanishing points. 2. vertical lines are not parallel 3. cube looks squished or distorted	Satisfactory 1. vertical lines are somewhat parallel 2. very few edges aim towards vanishing points.	Good 1. vertical lines are parallel 2. most of the edges aim towards the two vanishing points. 3. cube looks almost 3-dimensional	Excellent 1. side edges of cube aim towards two different points. 2. my verticals are parallel. 3. Cube looks 3-dimensional
Pencil techniques	Needs Improvement 1. messy shading. 2. edges are not defined and values run into one another. 3. paper tooth compromised.	Satisfactory 1. pencil lines are visible. 2. edges appear messy. 3. deep scores in the paper.	Good 1. pencil lines are somewhat visible. 2. edges are somewhat fuzzy.	Excellent 1. hard to distinguish pencil lines. 2. edges are crisp 3. no burnishing of paper.
