Hi guys
thks for the comments
i know this is the best place to make our hobby better

to answer the weathering first of all
i spray very thin tamiya buff through my AB
after that, i use very small amount MIG pigments, this is the first time ever i use this product, and the result very very beautifull ( this is not promotion part

)
apart from using MIG, i still use pastel chalk to add some more detail, or sometimes i mixed between MIG and chalk
and after read all ur comments, i decided to add some shellholes..any one could tell me how to do it ? and how far does the holes can penetrate ?
for the track, i will make some broken track links, to give an impression this TIGER already Rest in Peace
thank's for giving me such an idea to finish my model
