Possible suggestions (if it were me, I'd have to try them out before deciding, you may be able to decide more easily): 1. Try moving the planet down (or the viewpoint up) such that the curve disappears out of the bottom of the picture (and doesn't reappear; ie move such that the upward curve on the left vanishes). 2. (Having done 1) Move the spaceship up or down and a little to the left (that bright exhaust is one of the centres of attention - as I understand it, theory says it shouldn't be on the centre-line). 3. Add some fuzziness/blur/"matter being ejected effect" to the exhaust. (It may not be physically correct, but...) Or leave it alone - great pic!! (And I agree about the detailing.) Cheers, Diolma
