What requirements do you have for the gain and source impedance?

The most obvious error is the polarity of the 22µF capacitor is backwards, which the simulator probably didn't spot. In real life it won't blow up, but it will upset the DC operating point, because it will conduct DC.

the gain requirement is 4

The gain will be a little higher than that: about 4.4.

Other than that and the polarity of the 22µF capacitor, the circuit is good.
