You can't just name a ship Heetai Con and expect everybody to be civil about it. You brought this upon yourself so don't try and act like it's everyone else's fault. I'm not trying to be mean, this is just the way it is and if it wasn't forseeable to you then you're out of both luck and evidently common sense.
Spell it differently, but leave the pronunciation the same. Like Hitai Con or something. The drawing itself is very good, but a little more detail wouldn't hurt. Also the rails on the walkway look a bit tall. The helicopter is really neat looking.
