Learning about the value scale with ammolited ammonites!
A series of quickie paintings to study negative and positive space AND the analogous colour scale.
And my favourite so far, a piece inspired while learning about line. This wasn't strictly homework, but I had done a similar one of a pear (our homework was to draw four different versions of said pair) and wanted to do something slightly more awesome. I think Styracosaurus lends itself quite nicely to funky lines!
