Monitor Lizard (Colored)

I colored the goana after all:

Goana / Monitor Lizard / Varanus Komodoensis

It is nearly the end of the kindergarten year. Every year we have a new young guy (doing a voluntary year in the social sector) taking care of the kids. He´s been saving for a goana. This is the card he´ll receive with his leaving gift.
(I´m not really sure whether I should color it with pencil colors or not. Any suggestions?)
