OK, gonna hit ya with a few things that jumped out at me. First though, I should point out that I LOVE this dio base! The ice looks very real.
But the vehicle doesn't look like it belongs there, because none of that ice is on it. No mud, either. The vehicle is not wet, not muddy, not miserable-looking. It looks good, but needs to match its surroundings.
Next thing is the straps on one or two of the figures. Most have black straps, Y-suspenders, etc., but one or two of them have their straps blending into their uniforms.
Another thing is, I can't tell for sure, but I think I see dunkelgelb on the tracks, around the drive sprockets on both sides.
Last thing I'm gonna bring up is that some of the figures are both wearing cammo smocks, AND have cammo smocks rolled up on their backs. Seems like they should be one or the other, not both.
Other than that...
