I also second the model looks very good, even more taking in consideration your efforts in the making and the mentioned lack(???) of experience in AFV modelling, but that is your opinion only because I would not say it so by seeing the result...
I admire your good taste on the dark yellow / red brown camo scheme because you cannot see that combination on a Tiger often and they are very beautiful indeed, but on top of everything I like very much you ended making up one A/B sides model actually, because -in my opinion- the model offers two different images depending on the side you look at (with/without side fenders). A very clever way to exploit one model visually, well done.
PS: As for the diamond thing, David is one true Tiger speciallist so better is to listen his recomendations on time.
