hi
well i wish my first build had come out that well! its lookin good.
the only negative point i would make is the sand bags on the front look abit stuck on, there is no sag in them, but i guess they are molded plastic ones so there isnt alot you could do about that. prehaps on a future model try making them your self out of putty.
just a thought, dont take it as critisizm of your handywork, your off to a great start!
neil
