Use bright color eitehr for circle or its outer rim- say if inside color make it more bright purple - if rim make it bright golden - if you amke rim golden- make stars yeelow too. that will give it very bright and circus feeling, currently its looking very dull. If you make purple bright inside circle use white stars only.
Its coming out real nice -
Tip -Try making the curtains a bit more wavy and with more seams.
