i would say if your gonna keep that race portrait then change the color so it matches with the rest of the ships. Not necessarily the same color but something closer to blue.Also if you get doga3 you won't have tp worry about masking because you can render to a black background or if you want you can make the image and then open the motion desgner and put it in there. Just position the camera accordingly and you can set a black background. Thats what i did till i got D3. Should save you a lot of time.
