Very smooth, I like how you integrated your own style into it.
At first glance, though, it's kind of confusing as there isn't really a flow or focal point that leads to the characters.
Now don't get me wrong, I love the bg colours and how you did the characters, I'm just saying purely constructively, you could position them a little apart from each other or minimize them/ enlarge the background area.
i like it 8D
nice choice of colors on the chameleon too 8)
heres alittle something that would help. in doing BGs like this, you have to contrast the color of you subjects to the BG, so if ur looking at orange, you have to contrast it with its oposite color in the color wheel, which are the green 8)
or you could just do light and dark contrast to bring out the subject more ^^
