You definitely don't like slabs xD And they can give you much better curves than wedges.
It is a good idea to either throw away circuits from engines (preferable on such a small ship) or place ice above all the engine surface, leaving a gap for thruster plumes to spawn (less preferable on this scale).
Otherwise, the ship is great. Screenshots are not, though xD
I'd try a different angle, where the ship shape is revealed, not concealed by wedge reflections and Starmade light render troubles xD
