1) looks a bit glossy to me, and the picture is too blurry.
2) the pink is beautiful, except maybe at the firing end of the barrel. i especially love the pink lining, contrasts beautifull with the green.
3) the green mottling looks gorgeous. you may need to overshade/overhighlight this model a bit though to compensate for the mottling.
4) the detail bits (metal, gunner) simple do not contrast enough with the green or with each other. this washes the model's appearance out.
