Took the time to play around some more, a few little flourishes here or there. Important part is that I believe I've finally stopped nitpicking the engines.
I'd advise placing an engine to the lower front compartment, so it stays in flight and we don't have to go with the Black Hole method Katz presented. xD
I napped and woke up feeling way too tired, but still. I had some ideas so I reworked the engines again, this time around I think they're more firm and secure looking.
I played around some more today, aisde from getting started on texturing in some of the more simple areas I've decided to add an additional main drive in the traditional Rheinland style.
Turkish, I have to say that I am impressed by this model. You managed to conserve the typical Rheinlandish look and put it into some kind of tortoise-looking hauler. Great work!
I'd even say that you don't need the middle engine, as the ship isn't as big as a battleship and won't need the biggest engines of Rheinland.
