Good parenting

A mother trying to protect her two kids by intimidating an off-screen predator. The sack on her neck, fins on her head and wings are for intimidation only; she can not fly. When not feeling threatened, she can fold them and deflate the sack so that all parts that are red are hidden and she becomes camouflaged. The two kids she protects are not fully grown yet and still show their hatchling colors.

I just wanted an excuse to use my colored pencils again, really ^^
Medium used: Derwent colored pencils, mechanical pencil.
