Dunno, man, honestly looks good to me as it is. Doesn't quite fit with the vanilla high-tech, but it's exactly how I would imagine a ship in a hypothetical design line between mid and high looks like. So maybe instead of remaking this one make a few more in a smilar style?
Edit: I also really like the brown parts. It kinda looks like a brown ship encased in blue armor. Maybe even double down on the theme and make those secondary "holes" on the top piece brown as well.
