Try and build the pose on the pilot's character. For Roy it's all about being bad ass drunk'n cool.
And Hikaru can be the same, but a little more serious, especially in the 1S.
I can't explain it better for now, i'll be doing the same once i get the time.
All i know is once i get my Hikky 1A new 1/60 i'll have a whale of a time doing new poses the 1/48's can't. And that's alot!
When we get the 1D new 1/60 i'll deffinently do some clumsy poses for poor rookie Hikaru!
THEY BETTER INCLUDE MINMAY!
