This circuit works better than mine but still has a little distortion (the bottom part of a sine wave is more narrow than the top). This circuit is the same as mine except the voltage divider (R1 and R2). Your use of smaller resistors allows more current to flow into the base. Good job!
Well yes, for this simple amplifier distortion are unavoidable. The only thing we can do is to reduce this distortion is to add some negative feedback to the circuit. But more feedback mean less voltage gain, nothing is for free.
