I tried to draw a sphere, a box, a cone and a cylinder in the same space. Tools: charcoal, white chalk and toned paper.
The first one was drawn without any reference, but I looked at some reference before drawing the other two.
Things I thought about during the process: core shadow, cast shadow, highlight, reflected light, highlight on edges and gradation on a flat surface.
Is there anything I'm doing wrong, like the value changes or the placement and shapes of shadows? Let me know, thanks!
Looking good. Best to draw while you have three dimensional reference in front of you; it's an important part of the exercise (learning to collapse three dimensions into two). But these are nice looking drawings with attractive charcoal marks.
I was once on the receiving end of a critique so savagely nasty, I marched straight out of class to the office and changed my major (sketchbook).
@ Stoat: Yeah, I guess I should do some still life studies of these shapes. Thanks for the comment. BTW, love your sketchbook!
@ Quike Garcia: Yes, the last cube is supposed to be an open box. I guess I did well then. Thanks for your comment.
Pretty good; I think you could push it a bit further if you wanted to. Definitely have a set-up in front of you while doing these. I think you could refine the shapes more; they are a bit wobbly in some places especially your sphere and cones. Try to have more of a smooth gradation for your shadows. You can do this by sharpening your charcoal and going over your shadows over and over again until you have smoother values. It's tedious but it's good practice. Have a reference photo of a perfectly drawn shadow sphere or whatever next to you too just to see what you should be aiming for (but don't copy it!).
@ rex-craft7: You make some good points there. I think I was a bit careless about the shapes and focused more on the light vs shadow thing. Maybe I should even lay down a perspective grid and draw the objects more carefully. I did the gradation of the shadows mostly by blending the charcoal with my finger or a piece of soft paper. I might try doing it by building up the tones. Thanks!
