Hehe, I like the theme here. Flora and fauna coexisting in their habitat, It certainly is refreshing~
I haven't seen cool (like, the opposite of warm kind of cool) colors like this in a while. Your palette is well selected, and the various shades and hues blend really nicely, especially with that painty/brushy coloring technique of yours.
