Thanks maritiem and Mad_Fred. You must all just throw in tips and hints to work, if it is negative or not, is not dangerous. Only the vessels are the most realistic and detailed. Thanks again, really appreciate your attention to this work.
Smashing work, your extremely good at modelling!
Looking pretty complicated there, I think. BDW, how do you know the width of each thing while you have only the profile view image & some hull dimensions?
