Emerald Outlaw

Ya girl's on a roll! 
May's birthstone is emerald, but once upon a time it was also agate, and as of 2013 in Britain, it's also chrysoprase.  I tried to include some of all three, but chrysoprase kinda disappeared into the richer greens.  It's the paler, bluish tint you can see in some of the agate stripes and also around the face and belly.  I like how this guy came out looking a bit like a parrot, since I wanted to give him kind of a pirate/ viking vibe.
