The next drawing I completely forgot about; this is a drawing of a walrus (Odobenus rosmarus) cranium on display at the Smithsonian. This was shaded waaay too much, but the particular style of drawing I developed in high school called for really dramatic contrast and lights and darks, so that's what I'm stuck with.
The next drawing is actually pretty big; I finished this one on sunday. This is a lateral view of a 7-9' long (can't remember exactly) Sei Whale (Balaenoptera borealis) cranium on display at the UC Museum of Vertebrate Zoology in Berkeley. The drawing is nearly 2' wide.

The last drawing took a couple days; this one's of a pretty gnarly critter - the skull of Otaria flavescens, the Southern Sea Lion. The skulls of this animal have all sorts of grotesque knobs and protrusions. This individual wasn't too bad, but note the projections on the dorsal braincase posterior to the orbits.
