Hi Shwetaj,
Curly, short hair is not really a good idea for a round face. It will only emphasize the roundness.
Try cuts that fall just below the chin. Soft, graduated layers are a great bet because they make your face appear slimmer and tend to remove bulk and weight from the sides. Consider wispy and tapered ends. These de-emphasize the roundness of your face. Bangs are flattering, but keep them long or side-swept.
