What he said ^ , the PP2 may well be the hardest , to do right any way, there a so many subtle colour shifts and blends that are hard to pic up, and to do the PP2 or ROTJ and do them properly there is alot of unseen work
were the ESB is just flat colour coats over colour ,yes there is more regognisable scratchs but there is no mystery in painting the ESB, were the Jedi and PP2 have a much more artistic aproach taken on there paint aplication, if that makes sense
some people may not agree with me but thats the way I see it any way
