...oh my God they look bad!
Actually, I shouldn't say "they." The Snowspeeder looks pretty good, but the AT-AT?
It looks as though they took an "off the shelf" can of white spray paint with a bad nozzle and blasted the thing EVERYWHERE!
Some of the paint splotches are over close to 1/4" wide. They are round blotches, so it looks like it has spots or polka dots rather than snow.
On the good side, it is totally random, so there is a chance that you MAY be able to find one with very little "snow."
