The droplets/ghosts are my favorite. I love their face expressions. Though, the orange lizard at the bottom of the page the wraps around to the top, that was well done as well... I love things like that.
I agree, nice shading. The colors make it very fun to look at. Very up-beat.
The only doodle that irks me is the ghost/drop at the top of the page. What's that bump coming out of him? If it's a hand, why does he only have one?
But other than that, I don't have any real complaints. The other doodles more than compensate for the one-handed ghost/drop. Good job.
Words are pale shadows of forgotten names. As names have power, words have power. Words can light fires in the minds of men. Words can wring tears from the hardest hearts. — Patrick Rothfuss, The Name of the Wind
