Make the scale of the grass texture surrounding the platform smaller... Also, use more lights to make it come alive, use a spot on the statue, try a different sky showing some white clouds, right now it looks like an overcast day, and inasmuch as the rainbow is nice, you want to show the world that it's a bright happy day, at a park that people want to go cause it's a bright happy day.... :) Anyway, hope this helps...
