I don't agree, I think in designing such a fine piece of craft (possibly even in space, where there is no dirt!), you would take much care to keep it clean, and from being weathered.

Now whether it's built on Earth, on some futuristic space station, or a different planet, could affect that totally, as well as where it's been, such as having a heavy battle, by a big, soily, planet, with lasers and rockets flying into it, shooting up dirt to land way out onto one of the ships. 

But nevertheless, I think it'll be cleaned up time to time.

Bricks just sit there, on Earth, and nobody ever messes with them again. Depending on their location, they get eroded, some more than others.

I think it looks pretty cool, retro. But the main character (I think?) doesn't read totally well, I thought it was a duck for a while, but I'm pretty sure it's not, now. And, that wall tile looks really funky, and not like a traditional wall tile at all. I also think the inside background, that green wall, should lose it's highlight, to present darkness better. Especially being under that ceiling, I mean, there's no light in there, so how is it being lit up?

Right(ours) arm looks VERY cramped in, it would fit best, and add to the pose if you were to stretch his arm out into the air, like the left arm, and I like that little 'bump' where the elbow is supposed to be.

I think those who are still working on a tile should be reassigned or somethin'.

Much better his legs seem a bit skinny though.. Especially compared those arms and abs.
