Nice try... you have missed some basic details. 1) The Mantlet is ALL wrong. it still depicts the Russian version. 2) Both the cupolas are wrong, the Tamiya kit depicts the final cladded version, the Type 59 had the T-54A hatch. 3) You've missed a lot of the finer details such as conduits along the rear hull and the front LHS. 4) The Dushka cannot be used as the Chinese gun is different; smooth barrel type.
I applaude your efforts and subject matter though...
