Hie Leviann,

My name is Heiwa and i will try my best to critique your work.

Arrows: Lets look at your arrows first. Although your arrow lines are confident they are not the right shape. They expand and get too thin to show any dimension properly. Few of the arrows you have curves which are not intersecting. It flows beside the existing waves and hence this does not give the illusion of it flowing through space. I will suggest you to visit the Arrows exercise and video again and try to re-draw. It does not have to look pretty but few points for this exercise is to not have repeated lines. Do not be afraid to superimpose the lines on the arrows.

Organic Forms and contour circles: Good job on the organic shapes, they are simple and they flow in 3D space. The ellipse are curvy and not confident. For this exercise i would suggest you to try to focus on your confidence of the ellipse as compared to accuracy. Try the ghosting method for drawing the elipses. I see that you have large variations of the circles which are good as it gives more information to viewer on how the shape has turned.

Texture Analysis: Good job on texture analysis. You have manage to get important information out of only shadows. You have taken good contrast out of the image.

Dissections:. Overall good job here. You have not only broken the silhouette but you have but your texture surrounding the shape. Good job on that.

Form Intersection: Good job on form intersection. They appear to be in 1 3D space and have good guess of the intersecting boundaries between objects. Although common thing that i have notice in your exercises is wavy lines which tells me that you dont use ghosting as much. I would try to suggest you to use ghosting for draawing lines and in case of complex objects like cubes or cones you can place points as your reference and then using ghosting method again. Obverall these are good attempts.
