FriniK that shirt design is awesome, well done man.
Since i wasn't consulted i'll voice my views on whether it matters if it has GTR references on it or not... I don't own a GTR but that wouldnt put me off the idea of a silhouette of a GTR on the shirt. I think the GTR looks much better so it'd be great for the shirt picture.
Take the current design out forward by FriniK for example. The only thing i thought may be controversial would be the actual model of the car and the RB26DET/twin turbo text.
Sure, it looks sweet, but maybe just keep the design as is but remove that line which leads to the hood of the car and have RB25DET written on the side too.
The other key issue is, what model skyline do you put as the picture? Just 1, all of them or none? I think there would probably have to be all if you wanted to keep EVERYONE happy, so that being said, maybe just the graphics without that car would be suffice.
Personally i think that if you are the sorta person who is keen enough to get one of these shirts/jackets; then you basically have the skyline heritage & loyalty in your blood & wouldn't mind too much on what model car/design was chosen in the end.
Just my 2 cents worth.
