Thanks John
ModelMakerMike: The two main modifications I made were to fill in the open slots on the shoulders & scratch new details on one side of the ship.
The filling in of the shoulder slots were done by pulling tight thin PVC electrical tape over the slots on the exterior side,....then filling in the gap by pasting model filler on the inside of the shoulders:
The tape was carefully removed after a few days, naturally there was sinking of the filler but that was re-filled, being very careful not to destroy any panel lines.
The filled area was sanded smooth, again paying attention to the fine details by the manufacturer.
When I was happy that the filled area was polished to a surface similar to the rest of the model I used tape to plan out where to scribe new panel lines. I used tape that I bought for The Falcon, it's a flexible PVC tape but it's magnetic....so it's thicker than most & very flexible, so it will follow a curve.
I scribed the lines with a scalpel blade (I need to refine the lines I've done...still looks a bit rough)
The scratched details were made of card & bits of kits:
One part of the scratched part is made out of the material used on 3D posters (donated by my teenage son)
The grooves adds fine detail
