Critical, how can someone be critical. Really nice finish Tom.
Let's touch on something you said here, you said you sprayed pigments. I recall reading about this somewhere else but could not find the link when called on it before. Did you cover this on a previous post or are ya sandbaggin' on us? Tell us about spraying the pigments, what were you after and how did it turn out for you?
If it's the dusting on the armor plate I think you nailed it. looks like some build up on the bottom of the front plate on the RHS, like a puddle dried, not sure what the intent was there or if the light is hitting it wrong.
If I had to be critical, I think you need some more color in the weathering, can't tell ya what color but it looks a little monotoned.
But what can I say, I've been working on a firewall for 2 months now, you've actually gotten a complete model done!
Thumbs up big guy!
