sketch book work

uh my hand slipped while I was yelling about this

OF COURSE the first thing I draw from the TOA book is big brother Percy. Really, I wanted to draw something really sweet with Percy holding his little sister. But then I thought I wanted Annabeth in the picture. Then I thought what would happen if Percy had to babysit his little sis. And then this was born.
To set the scene: Sally is at a book signing and Paul is at a conference, so Percy and Annabeth babysit while visiting New Rome for college stuff. And of course, Percy has to show off the cute babes.
