The Circus

[Zadaben]

I don't really find the dark (black) line under the objects distracting, but I do agree that the ground is very boring. I do not know yet what I want to do with it, but I will hereby promise to change it into something better at some point.
For the background: What more would you want than a couple of clouds? I could create some objects in the background with one color slightly darker than the light blue, but I am not so sure if it would change this into something better... Any suggestions?

I think that you should add one or two more clouds, of varying sizes, but leave the colour alone, it is good.
