As with just about any model kit, it is really left up to the modeler to decide as to the amount of detail he/she wants to achieve.  This kit gives you the ability to add a huge amount of extra added detail. 

  I recommend that "IF" you do decide to add some of these extra details, that you read through the construction steps that came with the kit and then review what I did in the construction of my model.  This will help you to decide on a strategy to incorporate your added details into your model.
