Lovely design and color choices! I would put a little more love into the head design to match the design level of the body. Make the shapes a little more interesting. Great job!

Wow, great job Russell! Really like what you ended up with and how you used the lessons to create your own design!

Your images are too bright which makes it hard to see what you have drawn. Try to upload better quality images.

These images are very light, make sure all your lines are clearly visible. Otherwise I can't help you :)

Good job!

Make sure your minor axis is converging towards a point that's on the HL (in assignment 3, cylinders 20, 10, 15 aren't doing this. + in a 2pp; when the minor axis is perpendicular to the HL, this will be a vertical cylinder. (if you'd construct this in a box, the ellipses will be placed in the top and bottom plane of that box.) You have some cylinders where the minor axis is vertical but you've drawn the cylinder as if we are looking straight at it

Try to simplify what you see in the reference in to a simple mannequin. The goal is to understand the forms of these creatures. So it's okay if it isn't a perfect copy. I feel like you tried too much to make your drawing look like the reference without using simple forms.

Your boxes are a bit distorted, this is because your lines of your box aren't comming together at the same point. A box in a 3 pp has 3 vp's; 1 vp is on the left side of the box (all lines from the box that are going to the left need to come together at the same point), the second one is on the right side of the box. These 2 vp's are sitting on the HL. Now if we look down on a box then the 3rd vp should be below the box and vice versa. 

Good, now try to play around with different shapes of boxes. Right now you twisted the same box each time :)

Hello, you could use more simple forms. It's good that you established a box first for the general perspective. But try to simplify the hippo in the simple forms. Right now you've just coppied what you see in the reference. Your mannequin doesn't have to look exactly like the hippo you see in the ref, only the form/perspective needs to be the same. So try using cylinders/manipulated boxes only.

When we mannequinize a subject we don't want to focus on the details (ears, eyes, ..) We want to capture the general form/structure. It's okay if your mannequin doens't look exactly like your reference. So try to take a few steps back and use manipulated boxes and cylinders only.

Remember that when a vertical cylinder gets closer to the HL, it's ellipse should become more and more narrow untill it's eventually flat (right on the HL). Also, when we look up at a box (meaning the box is above the HL) the 3rd should then be above the box, not below.
