Here's some painted pics of the freighter. The sheen is a little too glossy for my tastes.
I ran out of my fav matte varnish and need to hit the hardware store soon to stock up.
I used a combination of weathering powders, and citadel inks over top of a brown spray.
The Impulse and nacelle decals were custom. The underside Bajoran Emblems were form a PNT decal sheet.
EDIT: Here's a few pics sprayed with Matte and photographed under different lighting.
