HGUC 1/144 Nu Gundam HWS

This is my humble attempt to straight build HGUC 1/144 Nu Gundam (Heavy Weapon System) model which I bought more that two years ago when I was in Japan. I've picked it up just recently from my "storage shelf" and decided that it will be my first (but maybe last) model which I will try to paint properly - like other serious but amateur modelers. I have already ordered some "chemicals" and tools but unfortunately I think that I will not make it this year because of my busy December schedule...

Btw. do you have any advice on which type/brand of WHITE color should I get for airbrushing this guy? I prefer acrylics, though.
