Heh, I maybe giving criticism, but I don't really mind your Hydral design. Like I said, its far more scary looking than old design which is plus. I'm sure I get used to it anyway, it is cool design, I just didn't think Hydrals would have biomechanical design. Then again, I have no clue what aquatic species living on ocean planet should have.*shrugs* Organic ships are usually bug alien stuff and aquatic aliens are really rare. However, you are pretty much right on that if these would have been first hydral ships I would have ever seen, I wouldn't have said anything negative about them. Though I will stand by that antenna looks bit silly.
I'll just say it that I'm just stating my opinion here and not complaining that you should change them just because my opinion is different. While all designs are awesome, we are allowed to state our opinions anyway, right?
