That is incredible, I can't believe you built that only after a 20 second combat sequence. I don't think I have ever seen a ship come out so quickly after its debute.
How are you going to manifest its glowie center in the sfc3 engine, may I suggest utilizing apha mapping in *.tga format? You can use it to get a translucent look. And then you can extend the glow by using the SFC3 glow effects.
Looks great, I wondered how fast this ship would show up, and now I am shocked that it was so soon.
