Well I've been thinking and wondering if we even need the rock grabbing arms on the bottom.
The other mining ship has them, and they work nicely for adding to the looks of the ship. However, maybe we can just say that the BMM instead uses tractor beams to move the rocks around, instead of just grabbing them with the arms like on the hegemon....Either that or make the arms more pronounced here.
As for the engines. Not sure what to do with them, as most Bretonian ships have this underslung engine design, well atleast their smaller ships do.
I would have finished more sketches, but a paper for class got in the way.
Throw around some ideas here and I may see what I can draw up later tonight when I get home.
