Default Developement of simple Class A Amp

Hi friends

What is the opinion about the circuit given below? The original circuit was from a Japanese site, '5 watts amplifierí; I made slight changes in the original circuit, since LTSpice don't have the components originally mentioned.

What kind of improvements can be applied in this circuit without making the circuit very complex? Since I cannot do it practically at this time, if anybody can construct it for checking the quality is welcome.

Blue wave form indicates the output voltage; green is the input voltage and red is the current through the load resistor R8.

Regards
Renjish
