Heroes of Olympus Addiction

I don't know exactly how it happened, but I finished all 5 of the Heroes of Olympus books and am now finishing up the last 2 of the Percy Jackson books.  Due to this phenomenon, I have finally been excited to draw again. 

To begin, I have sketches of Nico and Leo. (As per request of my little brother.) Reyna will be next. We'll see about colors later.

Comments/character requests are always welcome!
