Congratulations for a great skin...
Just a suggestion from a retired skinner....
If You select in Photoshop 5-6 stripes on your U-boat body:
- apply to that selection "brightness" -40%
You will get nice weathered "late-war camo" skin... in a 10 minutes

(You can also apply "color balance" green 6-8% to these stripes...)
