Jack Archer's ship is quite nice, but as mentionned, this texture looks like scrap metal... and Archangel, despite having a better texture (but the bronze like colour really has nothing to do on a rheinland ship...), the ship's general aspect looks too round compared to generally bulky-boxy rheinland original designs (except the "wheel-engine" as I call it).
Oh and I'm trying to understand how the hell to mod it, but I barely understands how milkshape works...
