Yes the turret design looks very much out of place and they don't seem to fit the round-ship theme. Depending on what you want the ship to do or be for makes some features of the ship need changing.
As I had said in an earlier post, this ship could be used for a space battle. If so then change the turrets to either AA turrets or more preferably a downsized version of the heavy turret, like using the vehiclescale event. These turrets could then be coupled with setvehicleplayercontrol events so that one can enter control and exit control of the turrets easily without the need for actually entering the vehicle. But if you don't want to use vehicle turrets then make a turret, have a button that does setplayercamera and then have another button you could press while in that view to fire in one direction. Or use events that cause any weapons to fire by them selves at stuff that enters through a designated zone.
And I saw that there are doors on the sides of it to get into it. Put unrendered bricks there so people could 'land' there and go into the ship, I guess. So ya.
I also want to know if or when you have this build up on a server cause I would very much like to see it.
