I’ve been following your thread with great interest.
Good modeling style and cool design, also the shading is looking good now… IMO in first textures your ship was loosing the scale but with the last updates i see were you´re going. I love the way the textures are revealing the different layers of the ship and helping to see the “deepness” of it. I agree with the lighting being an important factor whe it comes to scale. Maybe a little haze at distance helps in giving away his large size.
As for reflection or not, you could try to make it a little reflective but not much, because it could make the shapes hard to “read”… maybe a blurred reflection, where the near volumes would appear a bit more sharp then the far ones, totally blurred, and thus, not bringing up too much reflection “noise” to the surfaces shading… my two cents though.
The Gissler looks great, i love the helmet shape.
Keep up the good work
