The front and rear cargo areas need something so that they don't look quite so boxy against the rounded oberth saucer, I think.
maybe i should reduce the width
I don't know, just my opinion, I do like the the size tho and how the nice the top, side, and bottom views look. Maybe the detail lights and tractor beam you plan on adding will breakup the texturing a bit on the front and back. Great work and design! Few can pull I a truly original design like you have.
Thank you very much, i know what you mean by the texturing at the front and rear......i'll sort it
