Looking at things up close the colors didn't make much sense next to each other but from viewing distance it all came together.
I didn't feel it was more than four stars though because there were some changes I felt needed to be made. I did end up changing the funny firefly on the top left since the rendering makes it look like a dart-board and I also changed the face a bit so the unicorn actually has some sort of eye rather than a shadowed spot on it's face.
