what a strange and unique combination!
I am usually not a big fan of this style, but you've caught my attention.
you've picked the colors nicely, and different. the yellow is a color of light and happiness, and the group of animals seem to erupt from a chaos, which creates a contrast between mood, style and tones. the background is soft enough not to mess with your center image. this looks wonderful for a web layout, a sticker, it seems to fit in all!
