Best Buddies

It was a long time since I wanted to do a drawing of these four guys all together!
OMG, I love them together I love the relationship that I have established between the three characters of Rick Riordan and my OC.
Piper. her first best female friend (Annabeth is more like an older sister to Holly)
Jason. even if she thinks that she knows Jason for months because of the Mist, he and Holly became very good real friends during their quest.
Leo. her crimes buddy! They get along very well, even too much for Piper... Holly and Leo have been friends for a long time, meeting at the Wilderness School. The two usually finding themselves in awkward situations for some unknown reasons that they can't really understand (but Piper knows why).
