Holy freaking shit. This is pure awesomeness. I love it.
Don't apologize for not making a 100% remake of the original. This is not Classical Remodelling. Feel free to do every variation you'd like to do.
The guns look very good. As a nitpick, I need to say that these small "teeth" on the original gave a more aggressive look to the swarmers that suited them well, and I feel it lacks a bit on your ship. It feels a bit too flat for now. Just a thought.
Also, the Swarmers were firing blue bullets in HW1. Might want to do this here as well.
Any team colors on this ? I can see a red square on the side, team color or real texture ?
EDIT : Now what is that thing I can see on the bottom of the higgy MS ?
