This is what we literally work on in art. We've been doing this for about 2 fricking weeks. We have to draw some stupid skull and blocks, heck, skulls aren't even hard, and the boy that sat next to me basically drew Shreck and the other one drew Shreck's drugged brother.
Also we just draw in black and white, aka dark, light, and medium, like jesus we can still use values in other colors! We also have to use a black fat crayon as our meduim.
