I agree with @GBBUDD about the cover it up flower box on the little house. You could reposition the in-flow hose/ pipe towards the far side which makes it less visible as it goes up into the filter shed.
Nice collection of birds. If you go to one outflow pipe, maybe use super glue or construction adhesive to attach a bird on it so it becomes a perch? then paint the perch brown.
