Could you get a "baked" bloom into the effects? I'm not sure what you're doing to draw the lines, but if you could assign a bitmap to it, then it's almost just as good I guess...
Something's up with the grid placement though. It looks fine in the top down, but when everything turns sideways, it looks as if the grid is too high up/close to the ship, as if the center of the ship is also the center of the grid. Since the grid doesn't actually draw on top of the ship, the impression is that that the ship isn't centered in the grid.
Also, if it's possible, spawning a small point light under the ship would be fantastic. It's done in the retail .anis, and would look nice if easily implementable.
